Hey - turns out IRC is out and something a little more modern has taken it's place... A little thing called Discord!

the 4770 is slightly faster, but the 9800GT has PhysX support. not mch of a difference. Get whichever you like more.
Personally i would buy a 4850 instead of a 4770. The 4850 is abit faster and even cheaper.
If you can afford 10 or 20 euros more, get a 9800GTX+ card. Compared to a 4850 the performance gain is noticable and worth the money.
