I would completely agree that there's more emphasis on the graphics processing than the CPU.. someone who's building at a pricepoint of $650 is honestly not going to take advantage of Crossfire or SLI. They just want a budget gaming machine that doesn't break the bank. Here's what I would do:
- Upgrade the motherboard to
a 790GX chipset. (-$10 after rebate)
- Upgrade to the
Phenom II X3 720 (+$16)
- Replace the dual 4850s with
a single BFG GTX260 core 216 (-$40 after rebate).
- Switch to
the Antec 300 case. (+$15)
- Drop down a notch to
this power supply (-$10)
- Memory prices have gone WAY up across the board.
This is now the lowest priced 2x2GB set I can find on Newegg - same brand and it's an upgrade from DDR2 to DDR3 though. (+$20)
- Upgrade the HD to at least
a 750 gig (+$13)
Net change in price is about $5 and you'll have an overall MUCH faster and better quality machine.
