Hi all,
I currrently own a gigabyte 4870 512mb card and was hoping for any thoughts of adding another 4870 to go crossfire i have a capable MB and psu but does anyone considering it a mad idea and a waste of cash or should a just save some more money and go for a 5850, not really bothered about dx11 and have seen some impresses results of a 4870 in CF.

Ps this is the 4870 i am considering

Will it matter that this card is overclocked and mine is standard clock speeds for a 4870.

Cheers for any advice given.
 
Honestly, a ATI 5850 or something like Nvidia 460 or 470.

You are not mad btw a dual 4870 rig is still fantastic but you will use less power, produce less heat and get more consistent frames with a single card setup plus, dx11 as well.

In favour of the 4870 is the price. But sounds like you would need to buy another psu anyway.
 
2x4870's run everything fine @ 1680x1050 on my second rig, but then again a 5850 has the advantage of dx11 (really, REALLY not that worth it imo), but obviously the advantage of single gpu over dual is a bonus.

honestly, i'd stick with dual 4870's and consider upgrading to a 6870 in a month or 2
 
It's a shame you have a 512mb card, I don't think 512mb of g-ram will back up the horsepower of two 4870s. i.e. anything which doesn't fill the g-ram will run at a way higher fps than your monitor refresh rate but as soon as it is filled it will still be unplayable.
 
To be honest, the extra horsepower that adding another 4870 will give you will just be severely bottlenecked by the 512MB - you won't be able to add any extra AA or anything.

I'd sell the card and get a newer, faster single card.

Not only will you avoid any crossfire issues (I used to have a 4870x2, and I found crossfire to be ridiculously annoying at times), you'll no longer be limited by just 512MB VRAM.
 
Cheers for the inputs guys, gunna save some cash and get either a 5850 or if i can wait till xmas gunna get a 5870 . Not been a fan of nvidia since my 6600 and 8800gts both died a month after the warranty expired
