to tell you the truth, it depends. If the computer is high end and will last me long, I might pay around 1000. But if the computer will only last me a year or so, I'd want to spend around $600ish. What i've come up with is, ill get the E6320, and a XFX 7600 GT Newegg.com - XFX PVT73GUGD3 GeForce 7600GT 256MB 128-bit GDDR3 PCI Express x16 SLI Supported Video Card - Retail
With those two parts changed. The Price should drop from $1150 after rebates to around $850. Then later when the prices drop, go for a Q6600 and 8800 GTS. I'm still kinda...idk, but its hard to decide.
er....at this late in the game I would ALWAYS advise against getting a 7 series card. I mean a 8800 GTS 320 mb is only 250 after MIR!!!! Thats a friggin steal and that card can last you at least 2 years at very good performance. Compare this with the +125 dollar-ish 7 series cards and you'll see that getting a 250 8800 GTS just makes WAY more sense. Also if your on a budget I suggest going for a E6750 ( hopefully dropped below 200 soon ) instead of the E6320. Its just so much farther in terms of performance and OCing capability.
