The 7800Gt in particular is excellent value for money shame it's only for those with PCI-e
There are some very good PC games out there, Civ IV, AOE III, NFSMW, COD2 Quake 4 but nothing coming up in the near future that I'm all excited about at the moment.
I was looking at the XBox 360 and nothing on that really looks inspiring either. The last game I got really really excited about was GT4 on the PS2, but I've finished that and it looks unpolished and a bit shit compared to modern PC graphics.
Maybe the PS3 will bring with it a new Gran Turismo game that will get me into gaming again!
Civ IV and AOE III are hardly showcases of PC POWER though, as nice as they look for what they are. And what they are is not offering anything we haven't seen ten years ago with a few tweaks, sadly. I enjoy Civ 4 lots but it isn't making me go "Wow! See what PC can do!"
As for NFS MW, that's a console game so again not really all that exciting. I can't seem to get into it anyway. And the other two are probably superfine examples of the FPS genre but again do they do much that's not been done before? I'm just not excited much by them. 360 has exactly the same trouble at the moment, and given that the xbox turned out pretty unimaginative for games I don't hold vast hopes yet. Vive la Revolution.
