I'm looking to do some upgrades to my Dell XPS 630 Desktop that is over 3 years old. I have Everest and it says my motherboard is a Motherboard ID 07/15/2008-C55-MCP51-6A61Im35C-00 Any idea of what I can put on this motherboard? Currently it has a Intel E8400 Dual Core 3.0ghz CPU Sockets/Slots 1 LGA775 Motherboard Chipset nForce650i-SLI 4GB DDR2 unsure of speed - Everest Says 800mhz Memory Clock Dell 750w power supply I had dual Geforce 9800GT running, but a few months ago one went down, and I knew it was only a matter of time until another went down which happend Friday morning. So I went to Frys after work and picked up a Asus GTX550 TI 1GB GDDR5. For a $130 I feel pretty happy with what I'm seeing from it, but wondering if I should have picked up a 560? I know this computer is pretty dated, but it performs pretty well for what I use it for, but wouldn't mind spending a little money into it to see some noticeable increased performance. Just not in the market for a new computer right now, and even when I buy a new one I would still like for this computer to be able to perform. All suggestions are appreciated. Thank you.
