No it's not a dual core GPU, it's just two GPUs on one board. Think of it like a server board, has two processors. I think this is pretty good. Offering HD 2900 performance at a very affordable price. I may consider an HD 3870 now. Hopefully ATI's next generation GPU will wield some really nice results, this is a very nice shrink/revision though.
GTA:SA is a good choice, just put the detail level on low, which looks as good as the ps2 version, max out the draw distance which makes a pretty big difference in viewing the city, and I run it all at 1280X1024 pretty darn good. The game looks great at higher rez! Also try Homeworld which doesn't need much at all! OR Homeworld2, that game only needs an 800mhz processor and at least a Radeon 7500, which most onboard surpasses today. Unreal also runs pretty well on my system =D My system 1.0ghz PIII 512mb ram ATI Radeon 9550 256mb ram (OC'd to 9600 speeds)
