4850 CF or 4870?

[Dexmaus]

I've been playing Fallout 3 with everything maxed with just a single HD 4850 @ 1920 x 1200, feels a little laggy, so I want to upgrade my video card.

should I buy another HD 4850 512mb and Crossfire it
or
sell my HD 4850 and get single HD 4870 1gb?

I would sell the HD 4850 and upgrade to a GTX 260 video card instead. Fallout 3 does better on a Geforce GTX 260 vs a HD 4850 or HD 4870 card. Take a look

if you really want to wait, I already purchased a second 4850 for CF. I could post some numbers up when it comes in (this week..?)

edit: i'm also at 1920x1200, e8400@3.8

dude dont fuck around, just get another 4850 to crossfire it and it will be amazing. The 260gtx is only getting like 1 fps higher than a 4870 so you can also get that. But i think for you the easiest way would be to get another 4850 and enjoy the game. Thats what i would do.

Something to look at with Crossifre and FO3

Hmm, i dont no what happened in that review with crossfire, but with my 4870 CF setup at 1680/1050 i sit around 75 fps. i dont think i have ever seen it drop below 60fps even once.

4850 crossfire u are looking at around 20% (worst case) slower with would still be excellent performance.
