The thing that is frankly getting disturbing is the definition of a "Gaming" PC.
I am not talking about your PC but just the whole thing in general.
Why get an expensive ATX when a 150 dollar microATX has 1 slot for a video card AND has onboard which these days can SLI, Crossfire with the right card? Did I mention that many of these now have the ability to play BluRay with 7.1 audio to HDMI?
I was thinking back to the time I was planning on getting a 900 dollar or so monster build. It would have been obsolete in less than a year (Obsoluete has in modern games would not run at 200 FPS afterwards)
For anything source engine, Crysis, SH4 (and likely SH5), DCS Black Shark, Falcon 4 AF with Freefalcon, BluRay, HDDVD, HD youtube, etc... This with an Hybrid SLI will work JUST fine.
