$750-900 Gaming PC (first time builder)

APPROXIMATE PURCHASE DATE: 1-2 weeks

BUDGET RANGE: 750-900$

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: 1.Gaming 2.Gaming 3.Gaming ...if you know what I mean

PARTS NOT REQUIRED: keyboard, mouse, monitor, speakers, OS

PREFERRED WEBSITE(S) FOR PARTS: newegg.com to show the PC parts, I`ll be buying from a local Latvian site (m79.lv if that matters for anyone - most likely not) with less variety, but I wont have to pay for shipping and service is easily available.

COUNTRY OF ORIGIN: Latvia (Eastern Europe)

PARTS PREFERENCES: I love Intel & Nvidia (especially second) and I`d like to stick to those

OVERCLOCKING: No

SLI OR CROSSFIRE: No

MONITOR RESOLUTION: (1280x1024 with my superold LG FLATRON L1730S, but when I finally upgrade monitor as well I might go as high as 1920x1080)

ADDITIONAL COMMENTS: I mostly play RPG games that have lower requirements in general (or at least I think so), but as I`m not planning to upgrade for quite a few years (I`m using my current PC for over 6 years now which is well above average I guess) I`d like to get a decent build for a reasonable price.

I`ve spent quite some time on figuring out how much I want and how much money I want to spend on it and right now I`m mostly worried if all the parts (I believe they are pretty decent on their own) are well compatible and should work smoothly together.

WHAT I HAVE SELECTED:

Antec Three Hundred Black Steel ATX Mid Tower Computer Case - Retail

Seagate Barracuda 7200.12 ST3500418AS 500GB 7200 RPM 16MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive

GIGABYTE GA-EP45-UD3LR LGA 775 Intel P45 ATX Intel Motherboard

GIGABYTE GV-N250OC-1GI Rev 2.0 GeForce GTS 250 1GB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card

Intel Core 2 Duo E8400 Wolfdale 3.0GHz 6MB L2 Cache LGA 775 65W Dual-Core Processor

CORSAIR CMPSU-550VX 550W ATX12V V2.2 SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply

Kingston HyperX 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 Desktop Memory Model KHX8500D2K2/4G

The GTS 250 is plenty for your current resolution but if you go to 1920 its not quite enough, I would get a GTX 260.

I have an E8400 also and it is awesome (OC to 3.8ghz easy) but if i were building a computer now I would buy a quad core, even a Q9400 OC to 3.4 which is only 30$ or so more expensive. Or a Q9550. A quad would make your system a lot more future proof.
