I am building my first gaming computer. I am trying to keep it at budget price but still keep it as forward compatible as possible so that I can upgrade. I don't need a monitor. I already bought the case and the hard drive, because they were on sale. Here is what I have come up with so far.
MOBO: ASRock Z77 Extreme4
CPU: Intel Core i5-2500K
HSF: Xigmatek GAIA
RAM: G.Skill Ripjaws X Series 8GB
HDD: Western Digital Caviar Blue 500GB
GPU: XFX Radeon HD 6870
Case: Rosewill Challenger-U3
PSU: OCZ 650W
I plan on sticking with the mobo and cpu cause I really like the mobo for upgrading later. I was looking at upgrading the video card but I saw somewhere that if I got two of the cards I listed and ran crossfire they would be good. Would that be worth it?
