Will there be much difference between the 2 set-ups in 1920x1200 res? From the benchmark on recent and older games so far they yield almost identical results w/ 4870x2 few fps higher. I have a 4870 with HR-03 already thinking about cfing it or sell it then get 4870x2 (which will cost a lot more and stuck with stock cooler).

Get new CPU and mobo, crossfire on 4400+ will give you a bottleneck...

Nope, they're the same.

Just get another 4870.

Also you can go to User CP and the Edit System and put in your system specs as opposed to listing it like you did.

The 4870x2 will perform better due to having 1gb of GDDR5 (it says 2gb's but in crossfire it's one). Also the 4870x2 is slightly better than the 4870 1gb in crossfire.

I have both.

Go with the X2. at 1920x1200 with all options enabled it is quicker.

the stock cooler is fine.

get the X2, but focus first on updating your mobo, etc.

go into your User Control Panel at the top of the page, and then click 'add new system' and then fill in your specs there.

The 4870x2 is faster because it doesn't have to transfer information between two different cards.

Fill in your specs here.

Yes it does.

sideport is not enabled on the X2 (contrary to AMD's promises).

The X2 and a pair of 4870's in crossfire give identical results at any res up to 1680x1050. Above that the X2 begins to pull ahead to due the extra memory.

How do you figure? It's a single card(doesn't have to transfer between two pci-e slots), but with 2 cores on it.

X2. But without knowing the rest of your hardware, I wouldn't recommend crossfire since the stuff you listed in your signature says you have an SLI motherobard. So it's a no-brainer, X2 FTW...

The interface between cores doesn't matter--whether it's between 2 different pci-e slots through the crossfire dongle or a component built into the card, the gpu's and memories need to interface and communicate between each other--in the case of the 4870X2 and 2 4870's connected with a crossfire dongle, the performance is the same because the X2 is no more efficient at cross-gpu communication than through the pci-e bus/crossfire dongle.

Haha, I love how everyone points me at the spec section. I do appreciation to help, but I am planning to do an upgrade soon (920, P6T, 6gb DDR3-1333, 1kW PSU), so I will fill in the spec once I get my hands on the sexy Nehalem
.

Stock cooler is not "fine" for my ears (assuming it produces the same amount of noise as 4870), once the fan speed is cracked up, it gives me a headache. If I sell my 4870 for around 200 if I am lucky, and get a 4870x2 for ~500, I will be ending up paying 300 for R770 x 2 or I can simply get another another 4870 for ~220. that extra 512mb really worth 80 bucks ?

I think the extra memory with the X2 (assuming you get the 2x1GB model) is worth it if you're at 1080p resolutions or higher. I mean, a 4870X2 with 2GB (1x2) is better than crossfiring 2 512MB 4870's that is--for high resolutions anyway.

I think it's worth the extra money.
