The $530 Second Tier gaming build has been updates with a few minor (but exciting!)upgrades and is also price $20 cheaper than before. I swapped the older Western Digital 320 GB hard drive for a better SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM SATA 3.0Gb/s 3.5″ Internal Hard Drive -Bare Drive which gives you a much bigger hard drive, and Samsung drives have had a good reputation going for them.
As well, I have updated the graphics card used before in this build which was a geForce GTS 450 to a XFX HD-577A-ZNFC Radeon HD 5770 (Juniper XT) 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card which is at a fantastic price of $149 and should give you a great performance of 1920×1200 resolution in most games. I will be updating the other builds as well really soon, so for now enjoy!
