I need some opinions here. If you guys have multiple computers playing the hand-me-down-upgrade game you know exactly what I'm dealing with. I had 2 3870s and one died. To make a long story... System #1 main 3x pcie firstname.lastname@example.org 1 3870 512mb System #2 spare 2x pcie email@example.com 2 1950 256mb (crossfire) System #3 daughter's computer 1x pcie 3.4HT@3.4 x800 256 What I want to do is choose the best solution to get the best performance for all 3 systems. Option 1: Put 1 3870x2 in system1 and put my 3870 in system2 so I can upgrade system3 with one 1950 and sell the other 1950 to my buddy. (I'll get $50 for it) Option 2: Same as option 1 but put 1 4870 in system1. Option 3: Same as option 1 but put 3 4850s in system1. (most expencive?) Option 4: Put a 3870x2 in system1 and keep my 3870 and run 3-way crossfire. (Fast, cheap, but the other 2 computers remain unchanged and I don't get $50) A single 3870 is about as fast as the 1950s in crossfire so system2 doesn't see alot of improvement which isn't an issue. I think the 3 4850s would be fast but I can't upgrade later. I'm sort of leaning towards the 3870x2+3870 (option 4). That might even beat the 4850 3-way. What do you guys think? 3870x2+3870 vs. 3x 4850. What wins? My daughter doesn't have any complaints about her little x800. After all she's only 7 but LOVES World of Padman for Quake3. EDIT - I should mention I can't run a double slot card in pcie slot-3 because the HD tuner is in a 1x slot next to it. That's why I'd have to use 4850s (single slot) if I went with 3 cards. But I -could- do option1 and add another 3870x2 later.
