I'll use it primarily for gaming and music production, but for now, let's stick to the gaming part. CASE: Cooler Master HAF 922 MOBO: ASUS M4A89GTD CPU: AMD Phenom II X4 970 GPU: GeForce GTX 560 Ti RAM: CORSAIR DOMINATOR 6GB (3 x 2GB) 240-Pin PSU: CORSAIR Enthusiast Series CMPSU-650TX 650W HDD: Western Digital Caviar Black WD1002FAEX 1TB 7200 RPM SATA 6.0Gb/s 3.5 Monitor: ASUS VH197D Black 18.5" Keyboard: Microsoft SIDEWINDER X4 I already have a decent mouse that I use with my lappy. Are these compatible? I checked already, and everything seemed to be in place, but I'm also a bit of a n00b, so I could be way off here. And lastly, any recommendations/part swaps for a cheaper build while also maintaining a comparable level of power?
