Unfortunately, switching out the motherboard is not an option... I already looked into it. And don't say buy a new machine either.
However, if it'll run that stuff decently like you guys say, I'll be happy with it. In any case, I think it'll be better than the integrated intel graphics I currently have (and if thats not true, whats up with that?) Also, I read somewhere that the GeForce FX5700 series is the cheepest bare for the recomended
requirements of HL2... course that could be false, but it wont stop me from playing it
BTW- thanks for the link.
