Re: i7 and intel quad core(price vs performance)
Going quad would save you a bunch of money. You would only need a mb and cpu you could reuse your ram assuming you do not get a board that requires ddr3.
An i7 would be more expensive because you need mb, cpu and RAM and they are all rather expensive at the moment. With that said you would have the ability to upgrade later as you would have the latest intel socket (1336) and performace in much better.
Another option for you would be an AMD phenom 2 and all you would have to do is get the chip and flash your bios for chip support. I make this recommendation assuming you are discussing upgrading the system in your sig.
ASUS P6T Deluxe V2 :: INTEL i7 920 @3.4 :: XFX GTX260 :: 6gb Corsair 1600 :: Corsair 750TX :: TRUE 120 :: Samsung T240 24" :: Windows 7 X64
