Is my PC just too slow to cope with GTAIV?

CPU matters more than GPU.

I haven't tested yet, but I think it should work fine on my rig. See, there's no point in running a Pentium 4 , GTX295 and 4 GB of RAM or i7 with on board graphics.

since the game was designed to run 3 threads, it would make sense to get a Phenom II triple core or quad core
any Intel quads

yeah your setup is a little small for GTA4 even my Q9550 with crossfire struggles mainly cos of bad coding and the game itself don't like AMD GPUs much
