I am attempting to build a computer particularly for gaming purposes for around 1,000 dollarsish. So I've been doing some research and I've come up with a basic plan I have.
CPU: Intel Core 2 Duo E8500 Wolfdale 3.16GHz LGA 775 65W Dual-Core Processor Model BX80570E8500 - Retail - I believe this is a decent choice for what I'm attempting
Mobo: BIOSTAR TPower I45 LGA 775 Intel P45 ATX Intel Motherboard - Retail - I picked this one mainly because of its compatibility with my cpu and its good reviews. Is Biostar a good brand?
Case: NZXT Apollo Black SECC Steel Chassis ATX Mid Tower Computer Case - Retail - this one looks cool. Oh and according to a number of reviews it is quiet, which is something I'm looking for
Memory: G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model F2-8500CL5D-4GBPK - Retail - I think this is enough and fast enough for most games? I figure in the future i can always add or upgrade if I feel the need.
Video Card: SAPPHIRE 100225L Radeon HD 3870 512MB 256-bit GDDR4 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail - Okay so this is where I'm having a bit of trouble...is this a decent choice? or is it incompatible - I think it would fit into my mobo =/
HDD: Western Digital Caviar SE16 WD6400AAKS 640GB 7200 RPM SATA 3.0Gb/s Hard Drive - OEM - I like space? Idk
Optical Drive: SAMSUNG 22X DVD Burner Black SATA Model SH-S223F - OEM
OS: I was thinking Vista 64-bit home. Cause Idk, its not that bad is it - or just windows xp it up?
Few questions: (1) Will I need a power supply? (2) Will I need an external cooling system? - I may overclock.
