You do know that the 7900GT 256MB is better than a 7900GS+ right? That's even if you don't volt mod it and overclock it to 7900GTX clocks.
As for the next gen cards in June? Why on earth would anyone buy a 7900GT now on PCI-e and then buy the "next gen" in June???? HArdly a realistic comparisson - oh, hang on, you don't do those...
Why would anyone buy an AM2 or DX10 card in 2-6 months when practically no games will benefit from them until the second half of 2007?
I see you have no idea of value, because you'd be paying upwards of £500 for one game (Crysis) and the CPU and GPU would be old hat by the time games actually came out for it.
