Hello. I have been planning on upgrading my current computer (SOCKET 478 - Pentium 4 2.53ghz, 512MB RAM, ASUS P4V8XMX Motherboard, NVIDIA 6800xt 512MB, 450watt PSU) for quite some time now, in order to run future games such as Call of Duty 4. I don't want a really great gaming PC that will give me top-notch performance, but something that will be able to upgrade (video card-wise) in the future and will run Call of Duty 4 just fine (I was told it would run great). I have got much help from friends. My budget was $500, but I threw in just a bit more. Here is the setup I plan on getting: Newegg.com - Intel Core 2 Duo E6750 Conroe 2.66GHz 4M shared L2 Cache LGA 775 Processor - Retail Newegg.com - G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Retail Newegg.com - GIGABYTE GA-P35-DS3L LGA 775 Intel P35 ATX Intel Motherboard - Retail Newegg.com - XFX PVT84JUDD3 GeForce 8600GT XXX 256MB 128-bit GDDR3 PCI Express x16 SLI Supported Video Card - Retail Newegg.com - CORSAIR CMPSU-450VX ATX12V V2.2 450W Power Supply 90 - 264 V UL, CUL, CE, CB, FCC Class B, TUV, CCC, C-tick - Retail I will be keeping my current case and my DVD drive/burner aswell.
