I am looking to buy a new gaming machine and need to decide bewtween Intel Core i7 920 (2.66GHz) with a nVidia GTX295 (1792MB) card or a Intel Pentium Core 2 Quad Q9550 (2.83GHz) with ATI Radeon HD 4870 X2 (2GB) cards. There is only a couple of hundred between the 2, so I'll rather go for the best option. Does anyone have a view?
