Thats probably what I'll do, just get a 4870 Now then waiting until I get a 24" monitor and getting a 4870x2 soon after that

sorry for the slight thread hijack but its not worth starting a new thread over...

i am also going with the 4870s ....but with my board even though its crossfire
1 slot is x16 & 1 slot is x4 ....will the x4 bottleneck it to the point of the extra GPU just not being worth the buy...??

Why not just get a 4870X2, and put it in the x16 slot?

I really think you should wait until you get the new card and see what happens. In my humble opinion, unless you're going to buy both cards at the same time and just game with them for the next, say, couple years and not upgrade, then there's not a LOT of incentive to go multi-gpu vs. the newest card released--for multiple reasons. First of all, POWER--to run 4 4870's in xfire is going to take A LOT OF POWER! No joke--as opposed to just a newer card that will consume less power and give the same performance as two cards (crude analogy). Second--while there will always be an increase in performance going to a second gfx card, it's rarely worth it in price/performance--might as well just sell the "older" 4870 and buy the newer card that's release if you aren't able to game with your 4870.

So, take my x1950pro for example--I was toying with going xfire about half a year ago as opposed to upgrading to a newer card--but to be honest, given the games out now, it's absolutely pointless given the requirements of newer games--perhaps I'd get maybe 5 fps more will xfire in some games (and some perhaps more)--but certainly not double the performance.

Just some food for thought...

could do i suppose..... but when the 3870x2 came out i could not afford it & still cant ...& i know the hype surrounding the 4870x2 is gonna push up the cost more than hype surrounding the 4870..

still could be wrong ATI may still have more surprises to come...

Yeah I dont think there would be too much of a bottleneck

EDIT: changed the OP

i see people say this all the time and it is not always true. with 1 GPU in Crysis I get high 30s at 1280x1024 and with 2 i get around 55. these cards scale great
