I'm in the process of buying this custom built PC. I'm also wondering will Pcsx2 playground perform pretty reasonable with these features:
AMD Phenom II X4 940 Black Edition Processor @ 3Ghz Per Core Socket AM2+
8GB (4 X 2GB) DDR2 240pin 800Mhz PC6400 Memory
500GB SATA 300Mbps 7200RPM 16MB Buffer Hard Drive
AMD 780G Chipset Motherboard with HDMI, 8 Channel Audio, Gigabit LAN, SATA 300Mbps, USB 2.0
ATI HD 3200 Video w/Hybrid Crossfire Available
Yeah I think it'll work just fine for most games ;D
About your motherboard 780g, make sure that compatible and support with phenomII. as far as i know phenomII recommanded with chipset 790g and SB750 with update bios.

why not choosing an intel C2Q since GSDX supporting SSE4?
just my opinion =p
GSdx performs better with nVidia cards (the author Gabest has an nVidia card)
and personally i would get an Intel CPU instead of the AMD.
If anything it would run slower than a E8400 @ 3ghz due to lack of SSE4 support, and the integrated video isn't going to help you out too much either. It depends on what games you would want to play, but more games would run below 60fps than not unless you overclocked and put in a video card.
CPU: Core 2 Duo E8400 C0 @ 4.1Ghz
Mobo: ASUS P5Q Pro (2048Mhz FSB)
RAM: 8GB PC2-8500 DDR2
Video: Radeon HD 4850 512MB @ 790/1990mhz
Sound: ASUS Xonar DX, Alessandro MS-1 headphones
A Phenom II processor seems very capable to handle the emulation as an Intel C2Q could, but I think using an IGP isn't a good choice to move the graphic work. This choice is even worse if you would like to play at resolutions higher than the PS2 native.
So my verdict is: CPU=ok, GPU=look for a decent dedicated card.
