I got my card from Novatech. Bought it for £160 + free postage & packaging. I've noticed it's gone back upto £165.59, but it's still the cheapest 260 around that I can see. Ebuyer were selling a gtx 260 for £135, but it didn't say whether it was the 192 core version or 216, probably 192, so I went with the Novatech card instead.
For GRAW 2 I maxed everything out at 1280x1024 with AA smoothing off, AFx16, Physx on Extreme and was getting between 79-32. Overclocked my CPU to 2.67mhz and now it no longer stutters in fire fights. My CPU must be bottle necking the card. Still I thought with a GTX260 the FPS would be higher. It now plays smooth, well at least on the first level, so I'm happy.
