Re: Computer Build Compatibility
The motherboard supports "Quad-core / Core 2 Extreme / Core 2 Duo / Pentium", and your CPU is among that, so you're good.
The motherboard supports "8GB" and you want to install 4GB or Ram, so you're good.
The motherboard supports "PCI Express x16", so it will support your 8600GT, and it will downgrade your HD3850 (they're backwards compatible but don't perform as well).
That's the best I can do, but it seems that all works. I'm not qualified to say whether the power supply will power it all, but it seems like you'll be alright.
