What should I get?

Getting a new pc just need you guys to help me with my final decision what graphic card should i take.....
well i decided i will go with ATI because i have already 8800GTS since August 2007.

HD 4850 x2 2GB or HD 4870 Toxic 1GB.

where i come from (Israel) the HD 4850 x2 2GB is 50$ more the the HD Toxic 1GB

the computer i'm getting...

Core 2 Quad Q9550, 2.83Ghz 1333Mhz, s775, 12MB

Arctic Cooling Freezer Xtreme CPU Fan For (s775,s939,AM2,AM2+,AM3)


GIGABYTE X48-DS4 s775 C2Q 1600Mhz, Intel X48, DDR2 1200, 2xPCI-E 2.0

DDR II 1066Mhz 2x2GB OCZ Reaper HPC Edition Dual Channel

Western Digital 500GB 7200RPM, 16MB, SATA II

Corsair HX 620W Active PFC 12cm Fan Modular

Enermax Chakra ECA5001

Go with the HD 4870. The dual GPU cards (such as the 4870X2 and the 4850X2) have scaling issues. Plus, the Toxic edition has a better cooler .

The 4850X2 only has 1GB for each of the GPUs, so dont think that you are getting a massive amount of memory.
Its safer to go with the 4870 here, and with the "Vapor-X" cooler you could probably get a significant overclock.

Ok, I didnt know.

Well, another reason to get the 4870 is the power requirement for the 4850X2 (650W). Even with a good PSU like the Corsair, you are right on the border of the minimum power required.

What if i take the HD 4850 x2 2GB and add the Arctic Cooling Accelero Twin Turbo Dual Fans VGA Cooler‎? would you still go with the 4870 toxic 1GB?

Is it an LCD monitor ? If so you resolution should be 1280*1024. In that case the 4850x2 is overkill. I would go with the 4870.

You can not add that cooler.

AS of the moment there is no custom cooling solution available for this card.
I wrote both to Atric-cooling and Thermalright, and they both answered me the same way.
It's due to the placement of the capacitors and the Crossfire control chip in the middle of the card.

Never the less the card is awesome, just make sure you have proper airflow in your system.
If you play at high res, this card is the bomb. Also make sure you use Cat 9.1 or newer drivers.
Older drivers do not support Crossfire Dual GPU unless you are using 8.12 hotfix.

Only if you have a great air flow in your case, other wise they lower your temps only by couple of degrees, which IMO is not worth the extra $70 you'll shell out on those coolers.

Here is a link to the forum posting I did on Rage3d.com, there is another alternative cooling solution overthere:

What i Understand from you is the i should take the Toxic cuz the resolution and power

i prefer taking the 4850x2 2GB because in the near future i will get a bigger Monitor

i believe that the 620 crosair PSU will be enough and worst comes to worst if your right then i''l just get a better psu. But i learned to understand that it is safer to go with Toxic 1GB because the 4850 is created only by Sapphire, but it is a fact that the 4850 x2 2GB is a better card and i'm willing to take that chance.

thank you very much for you help.....All of you .
this was my first question i askt on this web and i am very happy with your Community thank you all for you help.

Proper air flow meaning You should have cold air intake, preferably from the bottom front side off your case, and hot air out take from the Rear, top side of the case.
Now in some instances it also helps when you have side fan(s) on the case side pannel that will provide the GPU with cool air from outside.

HD4850 x 2 is quiet when not doing 3D but when GPu is under load the fan noise increases substantially, and that is the only reason I could see of implementing an after market cooling.

I was actually thinking of using 2 of the ThermalRight 2 copper heatsinks with Fans attached to them. They seem to do a better job at cooling.

No problem.
One thing I got to warn you is that these Copper heatsinks are a bit on the heavy side, so a slight bending of the video card might occur.
Someone was suggesting to implement some kind of support to the far end of the card to prevent this bending.
You will se once you get the card. Its a real monster I think it measures around 11.6 inches

I am Jewish money aint a thing ....

just kidding i work in a Computer store if i don't like what i take i simply replace it and pay the difference with 20% worker's discount
