Is my GTX280 Artifacting?

[LupoLover]

Hi all. Been playing grid on my system

Q6600 @ 2.4ghz
2GB DDR3 1600MHZ memory
OCZ SSD
GTX 280 600mhz core and 1100mhz memory

Surley this system should play it at 1680 x 1080 with all setting maxed out? Miy system is jumping in game.

Do I need to clock My q6600 up abit? My GTX280 is hiting 77C load that too hot?

Any advice would be great

Thanks

Sheldon
