Reliable Graphics Cards

Hello, I could use some help in regards to picking a new graphics card.

My current system config is:
WIn 7 Ultimate
Core i7
12GB Ram
2x 150 GB 10K rpm HD's in raid 0 for boot drive
Various HD's for storage
EVGA GTX 295 (connected to 2 24" LCD monitors)
EVGA GTX 260 (occasionally connected to a 36" HDTV)
-both vid cards are standalone

XI makes the video driver kernels crash. I am running XI in windowed mode on the 2nd monitor that is not considered "main". I have tested at least 5 different drivers and cannot find anything stable. I am currently looking at purchasing a

MSI N560GTX-TI Twin Frozr II/OC GeForce GTX 560 Ti (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card found at:

Do you think this would resolve the issue I am experiencing? any comments or suggestions would be appreciated.

I have a very similar system setup and use two crossfired XFX Radeon HD5770s (about $220 to buy both). They work very well and support up to 6 monitors including DVI HDMI and DP outputs. Combined with my i7 they run 14 perfectly on highest settings. I have even configured them with a virtual machine to be able to play two instances of Starcraft II on my computer at once (with a friend and separate monitor).

They are 1GB 128 bit GDDR5 PCI express x16. Average temp. for Starcraft II makes primary card run at 50 degrees on highest setting. FF14 brings it up to about 65 degrees average running temp. Have never had a problem with the cards.

Hope this helps!

EDIT: Lifetime warranties too!
