The only problem is EVGA's 8800GTX are not £170, you would be paying a lot more. Have you tried the EVGA step up program? Its said to take a while and also due to the actual step up cost you might aswell sell it and buy the card and end up saving money. At the moment its £252, and in 70 days it would be no point upgrading to a 8800GTX as it would not be a worthwhile upgrade and also you cant upgrade to a 9 series product.
Pretty sure in like 2 months you will be able to buy 9 series through step-up. I think it is very good and 8800GTXs prices will drop dramatically with the rate that the graphics cards are coming out.
