I have an older mac w/LION 10.7.5 - if I upgrade to Mountain Lion 10.8, will it slow down my computer significantly?

I have an older IMAC - purchased in 2007. Works well. I have LION iOS 10.7.5 and want to upgrade to Mountain Lion 10.8. Will it slow down my computer? If so, how much?

Be sure you can upgrade your iMac:
Upgrading to Yosemite
You can upgrade to Yosemite from Lion or directly from Snow Leopard. Yosemite can be downloaded from the Mac App Store for FREE.
Upgrading to Yosemite
To upgrade to Yosemite you must have Snow Leopard 10.6.8 or Lion installed. Download Yosemite from the App Store. Sign in using your Apple ID. Yosemite is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
    OS X Mavericks/Yosemite - System Requirements
    Macs that can be upgraded to OS X Yosemite

2. OS X Lion and Mountain Lion aren't compatible with PowerPC applications. After upgrading, if you have a PowerPC application (as Office 2004, AppleWorks, old Final Cut Pro editions, etc.), they will be moved to a special folder and they will stop working. Check that your apps are supported > http://www.roaringapps.com
If you are unable or unwilling to update to Intel versions of your PowerPC applications (if you have any), you can install Snow Leopard Server (with Rosetta) into Parallels or VMWare Fusion and continue to use most PowerPC applications concurrently with Lion or Mt. Lion:

Have been using your products since 1984. Very sorry I upgraded to Mountain Lion. Time consuming AND wiped out 2007 Quicken. I guess it would have been too much trouble to have red flagged this situation ahead of time. Out of business, literally.

Have been using your products since 1984. Very sorry I upgraded to Mountain Lion. Wiped out all my old applications. Out of business until I get this fixxed. Can I go back to previous operating system? Time Machine?

Downgrade Lion/Mountain Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.
In the future:
Before upgrading consider:
Don't upgrade if you are in the midst of important work. Wait until you have finished.
If you are having problems with your computer get them sorted out before you upgrade.
Verify that any mission critical software will be compatible with the upgrade.

I have snow leopard 10.6.8 and want to get on iCloud which requires Lion... should I buy Lion at $29.99 now and upgrade to Mountain Lion whne available (I can't see where it is available for download yet) and what is cost of upgrade to Mountain Lion?

I would wait for Mountain Lion to be released. According to Apple, Mountain Lion will be released by end of July 2012.
It will cost you only $19.99 to upgrade. You can find all the details at the following link...

i have Logic Pro 8 on my Snow leopard macbook.Can I upgrade to Mountain Lion?

It's not a bug. Although Logic 8 will run under 10.7.x and 10.8.x the installer contains PPC code which simply does not run in 10.7.x, 10.8.x and 10.9. The app is fine, the installer is the issue.
Some research on this issue has led me to the conclusion that the commonly held conception that the installer has PPC code is flatly incorrect.
That misconception is due to the fact that the PowerPC dialog box is triggered by any attempt to launch the installer app.
The "bug" I reference triggers this dialog box; not PPC code within the Logic Pro 8 app.
At the end of the day, the result is the same: the installer app will NOT work in Mt. Lion without modification. I have been given a tip on how to make a modification that will allow an analogous program's installer app work in Mt. Lion, but since I do not have access to a copy of Logic Pro 8, I cannot test this theory.
So, yes, the best approach is to be sure it is fully installed before the upgrade!

I have a Macbook Pro v10.5.8, is it possible to upgrade to Mountain Lion as thats what the Macstore is telling me to do?

I'm really not sure what I should be doing, the MacStore keeps prompting me to install Mountain Lion but I dont want to buy it for it not to work on my mac.
My Mac is a MacBook Pro, bought new in 2008 running version 10.5.8 which is Leopard I think?
If you could help me with this it would be great as my version isn't supported by hardly anything anymore (Google Chrome for example).
Thanks
