2560 x 1600 resolution.

Do you think I should just get a 4870x2 now or wait until the next x2? I can get a 4870x2 350$ eh

what about a 4890 crossfire? Would this be worse for my resolution?

thanks
 
4890 Crossfire would be faster than a 4870 X2. If you have the ability to crossfire doing that is a better solution than the X2 since each card will run a little cooler and quieter, plus you can probably find the individual cards for cheaper than getting an X2.

A 4870 X2 2Gb, two 4870 1Gb or two 4890s would all be great choices for that resolution. Should last you a while too.
 
Depends on your motherboard and powersupply. If its a Nvidia SLI chipset, go for two 260 216 core's or 275's. If your motherboards supports crossfire or crossfireX I would say two 4890's would be ideal. But really don't know your budget or anything about the machine the said cards are going into. You could list out your systems specs to the computer you are thinking about upgrading and we could help you more in depth.
 
the only thing is my mobo is x8 pci which may makes the 4870x2 better

psu is hx620

really dont think 8x will make much difference than 16x since it still not use up the bandwidth yet from what I have know..

I could be wrong though..

4870X2 if you want to go for single card solution, dual card solution 4890 will be your best bet...

The HX620 is enough to handle any two GPUs. What's the exact make and model of your motherboard? You only have ONE PCIe slot and it's 8x?
 
It's probably a P45 motherboard. They have a single PCI-E 16X or dual PCI-E 8X slots. And yes the HX620 is powerful enough for Crossfire/SLI (see sig).
 
it's a p5q pro, I think the best bet is to wait for the next big single card, hopefully within the next few months
 
lodingi: I'm not sure if the 620 has the 2 8 pins and 2 6 pins needed... I could be wrong, does it?

Yes, it does. The HX620 has two cables each with a 6-pin and an 8-pin attached.

According to this diagram: http://www.hardwarecanucks.com/foru...83-asus-p5q-pro-p45-motherboard-review-2.html , the P5Q Pro goes into two PCIe 2.0 8 lane connections when using Crossfire. That should be more than sufficient to run any current SLI/Crossfire set-up consisting of two single GPU cards.
 
Okay well at this point the only thing that is holding me back from getting a pair of crossfired 4890's is the x8 pci thing.

From

http://www.tweaktown.com/articles/1472/intel_p45_vs_x48_crossfire_performance/index.html

it looks like there is a fairly big performance loss between x16 and x8.

Price wise:

4870x2 - $350
crossfire 4890 - $400

what do other people think about 4890 xfire on an x8 mobo, vs. a 4870x2 running at regular 16x pci (p45 mobo). I guess I could always try to sell my mobo to get an x38 or x48 but really dont want to go through the hassel. I'll probably end up losing around 50$ too...

thanks

Interesting article. I think the performance loss is more due to the chipset rather than actual bandwidth limitation. There's definitely a loss, but it doesn't seem to be that large on single slot testing - http://www.tomshardware.com/reviews/pci-express-2.0,1915-10.html . In either case, it might be worth it to hold out for 5870X2 - I just can't see spending more than $300 on old tech like a 4870X2.
 
yeah that's what I plan on doing

I just bought a single 4890 for 200 shipped to hold me over until the new 5870x2 comes out.

you bought a card to "hold you over" for 5-6 months? I would much rather have a card better suited to my rig and play games at higher settings now then to wait half a year.

I got the 4890 because I can always buy another and crossfire if I really want to before the next gen cards come out. Besides 1 single 4890 should be okay for most of the games I play. Anyways I'll wait until both nvidia and ATI have their next gen cards out so really it could be more than 5-6 months
 
You'll be fine with a 4890. I played most of my games (TF2, L4D, Fallout 3, etc.) on a 4870 512MB @ 2560x1600 and 50FPS+ before I got my GTX 295.

Depends if he whises to be fine... i guess it wasn't fine for you since you got that 295 hehe...

For the OP, If you're playing not intensive games, buy one 4890 or 275, that's if you plan on going GT300/RV870, if not get a 4890CF(careful with brand and acoustics) or a 295.

I'm an eye-candy whore :D. The 4870 couldn't do AA at that resolution, now I run all those games at 16xQ CSAA :cool:.
