OK. I game at 1680x1050.
Yeah, Peter.....I thought of that. But I will be selling my current mobo and CPU for maybe $110 or $120 so I might even out in the end. The EVGA GTX 280 is still going for around $450 on ebay also, take out commissions so I will be stuck at about $425 or so like you said.
$425 + $115 = $540.
ATI 4850 - $179
Q6600 - $189
Newegg.com - ASUS P5Q Pro LGA 775 Intel P45 ATX Intel Motherboard - Intel Motherboards - $149
$520
I love upgrading for free!! Might have to sell my RAM and get some new RAM too.
