I have an old PC ready for business and i plan to give it a new life. Cause i dont plan to build a new one, too expensive and i could use the cash for vacation during christmas :) 

Anyway, this is a gaming rig that should last for the next 2.5 years.

current system is:
E4600 + 2GB DDR2 PC8500 + 650W PSU.


I have to admit ATI is doing great delivering great performace card at affortable price, especially 4850.
But my current problem is to choose which card to buy. I have followed 4800 benchies and still cant decide between ( although we havent seen how 4850X2 will perform)

4850 + 4850X2 CF
or
4870 + 4870 CF?

what i know is:
4850X2 > 4870
4870 > 4850

thx

Indeed, they are great cards. However I really cant see the point in doing a CF setup unless for boasting rights, or to play crysis in very high resolution maxed. If I were you then go for a single 4850/4870, add another in future when it's needed and prices have dropped. Also whats your motherboard?

Yup, that should be how it lines up.

As for what solution is best for you, it really depends on your motherboard, monitor and what games you intend to play.
For many, a single 4850/4870 will be more than enough power.

If you are gaming at a higher resolution and have a P45 or X38/48 based Mb, 4850 Cf is a hell of a bang for the buck.
If you still need more power over 4850 Cf, the 4870x2 will give you a better bang for the buck over standard 4870 Cf.
At higher resolutions, the extra 512Mb of GDDR5 starts coming into play and has the potential for decent performance gains.

I would not recommend mixing and matching 4850 and 4870 based cards in a CrossFireX configuration.
All current multi GPU solutions use a technic called AFR (Alternate Frame Rendering). This works bye having each GPU render sucessive frames. For example, with a 2 way multi GPU setup, the first GPU will render the even frames and the second GPU will render the odd frames. With 3 GPU's, each GPU would render every 3rd frame. If you have one faster card and one slower card, either the faster one will have to slow down to match the slower one or every other frame will be rendered faster. This has the potential to give the screen a bit of a chopy feel (ala microstutter). I have never used CFX this myself so I can not say for sure if this issue has been resolved with newer drivers or not.

concrum wanting to build a PC based on ati.........:??: 
NEVA saw this coming....

anyway
if u dont want to get a new PSU, i say stick with either 4850x2 or 4870x2....whey are better performers that 4850CF or 4870CF

u will definately need to up ur PSU for triple card system and i dont think drivers are matured enof to makr ur money worth

The 4850x2 should be cheaper than a G280, and itll outperform it as well. If you think you can live the next 2+ years with a card thats a lil better than a G280, then go for that, otherwise go for the 4870x2. CFing the x2's will get you a performance boost, but not worth the cost, unless you just want the absolute best IMHO

nice find sarwar.

i have a 4850 right now, and kinda wanted to go 4870. but i will wait for the triple setup w/ the 4850 + 4850x2
