Basically have a tough choice between both these cards...which is best? 
Will be playing at around 1900x1200 or slightly below
Exact cards:
ATI Radeon HD4870 PCI-E 2.0 512MB DDR5 DVI/HDMI
GeForce 9800 GTX 512MB PCI-E GDDR3 Dual DVI/TV-Out
If one is better than the other...by how much roughly?
Thanks in advance
