|You should have done your asking BEFORE you bought a card. The 9400GT is fine for a HTPC but shouldn't be classified as a gaming card. It's a low end/entry level card & definitely can't take full advantage of 1GB memory, which is slow GDDR2 memory anyway.|
This review of the Asus 9400GT sums it up nicely:
"the Asus EN9400GT is not meant for 3D gaming in any way, shape or form. It might be possible to play Quake 3-era games on it, but anything more taxing than that and the poor thing is likely to cause it to burst into flames worthy of a Michael Bay film.
Of course, gaming is not what the ASUS EN9400GT videocard is realistically designed for. Its primary purpose is to give HDMI output to older PCs with PCI Express x16 slots that can't keep up with the taxing load of HD video decoding. In this regard, the EN9400GT works rather well."
