Possible to Crossfire 4870 and 4850? Tags: Radeon Asus Crossfire Graphics Last response: January 5, 2009 8:11 PM in Graphics & Displays Share dlh2109 January 4, 2009 6:14:26 PM Hi All, After a strange series of events with UPS and Newegg, I've ended up with two GPUs: a Visiontek 4870 and a Asus 4850. I've got the 4870 in my rig now and I'm loving it. Is it possible and/or logical to add in the 4850 for Crossfire? Will I see any gains? I usually play at 1680 x 1050 resolution. Here are my system specs: Q6600 at 3.4Ghz Asus P45Q 4GB Ram 750W PSU Vista 64-bit Thanks.

Might as well just sell your 4850 and add another 4870 if you need.

Get the answer rangers January 4, 2009 11:54:06 PM ^^fud fud FUD, the only limitation would be, a 48701gig being cut back to 512meg if you double it up with the 4850 512meg AdioKIP January 5, 2009 8:11:35 PM Rangers is correct and so is Kingtz. Crossfiring a 4870 and a 4850 is going to bring the 4870 down to function as a 4850 BUT this is still to your advantage as 2 4850's easily beat out 1 4870....and its costing you nothing...
