It's not the size of the monitor that matters, it's the resolution. You'll get the exact same FPS on a 22" 1080p monitor as on a 32" HDTV. For 1080p, one GPU is enough, especially on a limited budget like yours.
For a gaming PC at this price, I would definitely leave the SSD out. They're still very expensive, it'd be better to wait until they reach the $1/GB level or lower. All an SSD would do now is take away from the CPU and the GPU, since everything else is about as cheap as it gets while still being good quality. The CPU and GPU primarily determine how long it takes until you feel the need to upgrade again (hence the overclockable 2500K and a video card with 2GB VRAM).

🙂. Would not be surprised if that XFX PSU ran out of stock soon, the 550W version already did.
Agree. The good part is, a 30% overclock on a 2500K is perfectly achievable with stock voltages.
