Sold my 2x 88GTS 640's for £140 and bought the xpertvision GTX260 for £180. Bye bye SLI issues!!
I am very impressed with this card. Medal of Airborne for instance is now playable and I've nearly finished it today. In SLI it was like running through mud that I just gave up.
IN 3DMark it is on a par with the GTS's but in all games it is better. I only game at 1680x1050 and with this card I can crank up the AA & AF and have smooth gameplay. I did consider the GTX280 but the heat issue put me off and the 4870X2 but it's not out yet.
I just thought the GTX260 was a "bargain" only costing me £40.
