I'm also supporting the 955 instead of the 965. The 200MHz difference in operating frequency is easily made up, even at stock voltages, by raising the multiplier a single notch. The extra ~$25 would be better off being put towards a GPU upgrade seeing as the OP stated this build prioritizes gaming. In my opinion the 5770 is the weakest component in contrast to the rest of the build. Unless you plan to Crossfire two 5770s in the future; I'd highly recommend a stronger GPU if you're planning on a single-GPU setup. The single 5770 just seems like a weak link compared to the Mobo/CPU you had selected...especially if this is suppose to be a gaming rig where the GPU is practically the core component.
Even though it's running $95 more than the 5770 right now; I'm going to suggest the recently released 5830 (
Sapphire 5830 - $265). The 5770 is somewhat held back by its 128-bit memory bus and in the benchmarks I've been reading, the new 5830 typically outperforms it by around 15% in most games. I guess I'm just not that impressed with the 5770's performance as a single GPU solution; seeing as it gets bested by the 4870 in several instances.
EDIT: Actually, upon further research, I'm retracting my suggestion of a 5830. It looks like the performance increase over a 5770 is not significant enough to justify the $265 price tag on the 5830. Apparently the 5830 suffers from lopsided architecture and doesn't keep up with the rest of the 58xx cards.
My revised suggestion is to either "go for the gold" and get a 5850 (keep an eye out for a sale/rebate to get one under $300) or plan on getting a second 5770 to Crossfire later on. Either way the 5770, being priced at $150-$160, has more bang for your buck than a 5830. I suppose this means a single 5770 is still more cost-effective than a 5830 so I suppose you could make due with a single 5770. I'm pretty disappointed with the 5830 though; it performs more like a 5790 than a 58xx card.
To be honest, for a truly gaming-focused build, if you're considering making the $95 leap from a 5770 to a 5830, I'd actually suggest going all the way and throwing down an additional $55 to make the extra hop up to a
5850 for $320.
If you are sticking with a 5770, I have to advise against getting a XFX card. I love their warranty policy; but XFX cheaped-out and cut corners on their current 5770s by going with a "custom" cut, non-reference PCB which is inferior to the reference PCB for a variety of reasons. Check this
thread here regarding XFX cutting corners on the current 5770 batches. Also, IIRC, Sapphire is the official partner with AMD for ATI GPUs and from what I've gathered they seem to have the lowest percentage of flawed/defective units. I'd suggest this Sapphire instead of the XFX:
Sapphire HD5770 (Juniper XT) $160 - $10 rebate = $150

He's right about checking the combos on newegg though...there's some seriously great deals to be had. Here's a link to the same combo with a 955 (C3 revision) instead of the 965 for $26 less:
AMD Phenom II 955 C3 + GIGABYTE GA-790FXTA-UD5 + Free MW2 - $345
If you're not sure about the 955 vs the 965 (or before you ignore the those of us advocating the 955), you should check out
this thread here where people are reporting their overclocking results with the 955 vs the 965 and discussing their findings.
Also, make sure you get the C3 revision of the 955. It outperforms the older C2 "stepping"/revision chips and iirc also has improvements to the sketchy IMC issues that Phenoms have been dealing with. The C3 revisions also OC better in almost every instance as well.
Every newegg link in this thread so far points to a C3 revision chip; but I'd suggest checking out
this thread to make sure you know what you're ordering before you pull the trigger or if you end up ordering from somewhere other than newegg. Basically, Phenom II part numbers ending with
GM are C3 revision chips, avoid the C2 models with part numbers ending with
GI.
