Hi all, and compliments of the season.
Looking to get a new desktop early in the New Year, to be used for video/audio editing, rendering, coding and some games. I've taken the following spec from the Titan Lite options as I was going to get a ready-built system from OC, but figured I'd see if I'd save much by mixing and matching components. I know nothing of overclocking etc, so go easy on me
Antec Three Hundred Gaming Case
Intel Core 2 Quad Q8200 2.33GHz (1333FSB)
Arctic Cooling Freezer 7 Pro CPU Cooler
Asus P5Q Deluxe Intel P45 Chipset Motherboard
Corsair 4GB DDR2 800MHz Memory (2x2GB)
ATI Radeon HD 4870 512MB
Seagate Barracuda 7200RPM 500GB SATA II
Pioneer 20x DVD±RW Dual Layer ReWriter
Corsair TX 650W Power Supply
Microsoft Windows Vista Home Premium 64-Bit Edition
Logitech 5.1 Surround Speakers
Dell S2409W 24" Widescreen True HD LCD Monitor - Black
I have a keyboard / mouse I'm happy with. That lot is just over £1220 inc VAT, and I'd rather not pay more if I can help it. Not too fussed about the case, but do want it to be pretty quiet and power-efficient.
Suggestions?
