this ( MSI NX 6800 ) or this ( Asus 6800GT ) Money is somewhat of an issue - my current Geforce Ti4600 isn't pulling some games as well as I'd like for it to, so I figured I'd go for an upgrade. Is there a noticable difference between the two cards? Quality or performance wise? I love to play at 1280 x 1024 resolution with all settings churned way up, and HL2 is my favourite. Thank you!
