N9800gt-MD1G -- does it work in a pcie x16 1.0?

Question

just purchased an MSI N9800-MD1G, the box says pcie 2.0 slot but my current motherboard only has 1.0 slots, i plugged it in and the card doesnt seem to be operataing at capacity like its in low power mode. Does it get enough power from a pcie 1.0 slot? the card is a power saving card so it uses less power in idle mode but its not performing under load either. Also the card doesnt come with a pcie supplement power input either like a regular 9800gt.
-- any suggestions?

Answer 1

Since it has no extra power connectors, all it can get from the PCIe slot is ~75W, thats the most the slot can provide.
Furthermore and no offense, but since it has no extra power connectors and the core is only running @550MHz, dont be expecting GTX performance.
Its become sort of a budget/powersaving card, since its clocked down and stripped of its powerconnector, a normal 9800GT has its gpu running @600MHz or higher.
If you had one with 1 or 2 connectors, speeds and performance would be higher, since more power could be delivered that way.
Look here for specs:

What games are you playing with it and on what resolution? Most games should be good playable running them @1680*1050 or at lower resolution, going higher would mean big performance drop.
Run a 3DMark06 test and compare your score with others with similar card to see if scores are up to par.
