Budget was $750. Objectives: 1) a very good video card for gaming on a budget build, 2) excellent cooling from case and cpu cooler to allow for Overclock potential.
FX 6300 benchmarks showed performance comparable to better Intel I-3 and slower Intel I-5. Haven't overclocked yet, but it does seem pretty speedy.
MSI 660 gtx had great deal on Newegg. Positive reviews from majority. And Twin Frozer design for excellent cooling.
Asus MB M5a97 R2.0 -- probably should have gone with Asus 990 chipset board for another $20 or so. Research led me to Asus boards and I do like the layout and manual. I did check their "approved" memory list when purchasing the Sniper 1866 memory (another good deal from Newegg). Azza Toledo 301 case was a pleasant surprise and I think it's funny that I don't see any builds here using this case. Sturdy, pretty well laid out. Added one fan(exhaust blowing out of top rear of case) to the included three (120 mm low front intake, oversized 220 MM? side intake, 120 mm exhaust top of rear panel). Azza Case features one usb 2 and one usb 3 front panel plus audio ports (mike and speaker). Biggest hassle with case is screws (2) that hold top panel to case. Near impossible to screw in one when MB and other parts installed. Plan ahead for any fan, liquid cooler, and led lighting before getting to involved in build. I also planned ahead routing 24 pin PS cable and PCI power cable before mounting MB, but I had been warned about this while researching Computer building. Also, side fan on case prevented using those taller CPU Coolers. But I think I prefer this solution with fan blowing downward on CPU, Memory and MB. Install sequence went like this: Install cpu, install memory, install cpu cooler, then put MB in case. XFX power supply was probably best deal we had. Semi-modular, great deal and a Seasonic design. Again -- Newegg. CM GeminII S524 was easy to install (followed recommendations from reviewers on web sights like newegg and amazon). CPU temps (stock) run at 29C idle, 41C with prime 95. Very happy with temps. And actually all temps MB, CPU, Video card, Hard drive are excellent. Credit GeminII S524 for MB and CPU temps. Cable management worked out pretty well I think. Had no experience with Molex connections and now I have the proper loathing that other people have detailed.
