Looking to Upgrade LGA775 Processor
I've been in the process of upgrading a computer I got from my church for ~$20 a while ago, and I've already purchased a new graphics card (GTX 660). Based on my machine's expected performance on newer games, I came to the conclusion that the CPU needs to be upgraded. It's a Pentium D 945 dual-core at 3.4 GHz, but I think it's the 800 MHz front-side bus that's being the slowpoke.
I looked into the top-performing LGA775 processors, and apparently the top three were the Core 2 Duo E8600 (3.33 GHz dual-core, 6 MB cache, 1333 MHz FSB), the Core 2 Extreme QX9770 (3.2 GHz quad-core, 12 MB cache, 1600 MHz FSB), and the Core 2 Quad Q9650 (3 GHz quad-core, 12 MB cache, 1333 MHz FSB).
The Core 2 Duo is about $50 on eBay, the Extreme is $400 on eBay, and the Quad is $150 on eBay.
I'm not sure which I should go with. I'd want to get the Extreme, but there's no way I'm paying over $200 for it, and the other two seem almost just as good.
Which one should I get, and where should I be looking?
