Ok heres my advice:
If money is an issue(if you have a budget which he does) then drop the ram, buy this ram:
Computer hardware and software at amazing prices, available online from Scan Computers UK thats £35, if speed is an issue for him then you can easily overclock this ram to 930Mhz, i done it and its stable for me atm (970 was stable but then randomly failed on second boot), best of all, warranty covers overclocking as long as you dont up the voltage over its rated, the one i advertised is 2.1V.
This motherboard is good and future proofed more then most,
Computer hardware and software at amazing prices, available online from Scan Computers UK £90, i paid £99 for it and works wonders for me.
Dont get quad, dont even bother with a budget like that, hes a gamer right? the only games that support quad are crysis and supreme commander, minimal difference with crysis compared to dual, i havent seen a difference. I recommend something like, e8400
Computer hardware and software at amazing prices, available online from Scan Computers UK £136, gone up but still good price, i have it and totally recommend it.
If you want to overclock in the future, spend the money saved from going dual core etc on water cooling.
Any other questions?
