So i noticed on high settings on my HD 5870 that i get a little lag so i was gonna buy another HD 5870 on ebay and crossfire them but the going rate is about $200 for used and $300 or $400 for new if you can find them. So now i'm at the point I don't know what to do, if I should get a second 5870 or get a new card. If a new card a ATI or GTX? Seems like allot are going to GTX. So I really don't know what to do. Any Ideas?
