Want to upgrade most of the internals. I could use a new hard drive, but I don't need anything huge. I probably have maybe 2 or 3 gigs in music, and I don't keep a lot of games on the computer. So a smaller, faster harddrive would be best. I don't want overclocking speed, I just want something that is fast in stock mode. Reliable. Will last a good 4 or 5 years. Here's what I'm thinking: Processor: Intel Core 2 Duo E8400 Wolfdale 3.0GHZ LGA 775 65W Dual-Core Processor Model BX80570E8400 ($165) Motherboard: Asus P5Q Pro LGA 775 Intel P45 ATX Intel Motherboard ($115) RAM: G.Skill 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model F2-8500CL5D-2GBPK ($40) Video Card: EVGA 512-P3-N975-AR GeForce 9800 GT 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card ($125) Hard Drive: Western Digital Caviar Blue WD800JD 7200 RPM SATA 3.0Gb/s ($37) So far looking at about $482 for the above. I've built one or two in the past, but it's been at least 6 or 7 years since the last one, and I've forgotten most of it and/or been left behind. Is all of this compatible? Is it a good bang-for-buck setup? Question on the RAM... my motherboard specs call for DDR2 1200. Will DDR2 1066 screw something up? Is it worthwhile to spend twice as much and get 1200 RAM? Question on the Hard Drive... what is SATA? I think mine have been IDE in the past. Is it a different connecting system? Is this better than IDE? Will my motherboard support SATA? Thanks!
