MSI R7970 Lightning BE // Underperforming

Question

I recently bought an MSI R7970 Lightning BE for my new pc which is an Intel 3770k on a z77 Asus Sabertooth motherboard.. I'm using a 750watt power supply on a single 12v rail.. This card does high FPS but where it is failing me is mouse movement. If you walk back/fowards/left/right the gfx card is a champ, but if you're moving forward while moving the mouse everything stutters. I've tried MSI's drivers as well as newer non-msi drivers and they all pretty much yield the same result.. The major issue I have is the same issue persists on the lowest graphics settings 800x600 with all effects off or the highest graphics settings... What sort of stuff should I be looking for to rectify an issue like this?  This is truly driving me mad having just spent $500 dollars on a video card, I am pretty sure this video card should be destroying graphics.

I've tried 5 different mice... razer naga(wired), old school dell usb mouse with ball(wired), logitech(wireless), wireless microsoft mouse 5000(wireless) x2. I have a logitech g600 coming in the mail in a few days and i've tried different keyboards.
I've tried the msi driver disc that came with the product, also the newest msi drivers posted online the msi website as well as different versions of catalyst v12 and different versions of catalyst versions 13: 13.1, 13.2 and 13.3. Some perform better than others but none perform optimally as they should. VSync helps with screen tearing but not the sort of issue i'm seeing.. I've tried LN1 bios switch and LN2 bios switch which dont yield much of a difference.. I will upload several videos with FRAPS if you would like.. It seems to capture the problem the best. I'm using a NZXT HALE82N 750 watt power supply and i've done mannnnnny fresh os installs and bios tweaks.. even switched mobos from sabertooth z77 to a p8z77 pro and back to a different z77 sabertooth board.. tried hz limiters and fps syncing software(dxtory, radeon pro, msi afterburner, ccc, trixxx, iTurbo). I dont think this card should perform this way with stock settings for mobo/proc/gpu.. Nobody would go through the hell i'm going through to get video games to play on this card. ;/ After 3 weeks of trying various options i've started trying benchmarking software like unigine heaven, kombustor, 3d mark 11, performance test and even furmark.. I can see the same issue in heaven/3dmark11 and as well as furmark. in furmark with the fan set nominal @ 100% the card goes to 98 degrees celcius in 20 seconds(is this normal?).. Games I see issues in is new Tombraider, Bioshock Infinite, Skyrim(this card should destroy) and BF3(this card is known to destroy). the issue doesn't exist if walking forwards, backwards or strafing left or right... it only shows up when walking forwards or backwards while strafing left or right while panning the camera with the mouse.. same issue on lowest graphical settings @ 800x600 or highest graphical settings in 1920x1080.
