New Graphics card for 680i SLI

I'm looking for a new graphics card at the moment but I don't know whats compatible with my system.

My System:

Power Supply: Theramtake Toughpower 850W

Motherboard: XFX nForce 680i SLI socket 775 ( 2xPCI-Ex16)

CPU: Intel Core 2 Quad Core Q6600 2.4GHz

RAM: 4Gb

Windows XP

Current graphics card: GeForce 8800GTX 768MB (This went haywire on me last week)

I was hoping to get a Nvidia GTX 460 1Gb but I've no idea if its compatible or not. If anyone has any ideas on what Graphics card is compatible or any recommendations it wou;d be much appreciated

Thanks!

Yes, a GTX 460 1GB is compatible. You can run any graphics card that works with a PCI-Express x16 slot on your motherboard.

Thanks for the replies.

Not exactly sure what happened to my 8800GTX but I was playin COD MW2 and the game froze and the graphics were messed up. I restarted and the graphics on start up were fuzzy and when it got past the windows startup the screen just started flashing.
