[NIcaBoy]

Hello all,
I would like to change pc. I found a lot of good things for various elements, but I still ask myself the question for this famous graphics card.I hesitate between 4850 and Ati 9800GTX +, all at Gainward I think. Could you enlighten me?
The rest of the configuration:

Advance Housing PC Turboost
Motherboard ASUS P5Q-PRO - (I hesitated with a gigabyte GA-EP45-DS3R)
Intel Core 2 Duo E8500

Memory Kit of 2 bars CORSAIR DDR2 PC2-6400 - 2 x 1 GB (2 GB) 800 MHz - CASE 5 - TWIN2X2048-6400

Thanks in advance for any help.

I am not sure that 4850 is better than the 9800 GTX +, it is better than the 9800GTX, certainly, but for the GTX +....against by if you take account of the 4850 Gainward (golden sample), I thought it was better, and that is what I read in a very comprehensive test is the best of 4850, 10 to 20 % Gain perfrence... approach it very often in 4870 (most of the time, there is rarely more than 6-7 fps diff between 4850 and 4870 GS and, in some cases, the 4850 GS, goes some tenth of the 4870 fps)
then my (very) humble opinion, a 9800 GTX + 4850 is better than normal, but the 4850 golden sample and better than the 2 previous, for a price almost identical.

Of the total, between 780 and 810, according to the following sites and if the 9800GTX + or ATI 4850
So I hesitate for each .... ati 4850 shows the past few months its best-quality, and the 9800GTX + is more recent ... to whether its value for money is worse drivers of a poorly defined?

In any case thank you for your support

Hard disk: ok
Bottom: ok
A pro asus p5Q only if you intend to make the crossfire, the Asus Otherwise p5Q big enough
Processor: ok
Operating system : ok
Memory : g.skill prefer the pk
Food: A corsair vx450w would largely the case with your config with a HD4850
Graphics: The HD4850 Without hesitation Golden Sample This is the best HD4850:

For food, do not aim so high. Takes rather a VX550, and highlights the difference in rams G. Skill in CAS4.

Thank you for your advice for the RAM.
To map I think I have to look Gainward 4850 GS thus .

The 4850 and more powerful than the 9800 GTX + if you want to have the same power as 4850 with 9800 it will need a 9800GTX "V2". It worth a normal 4850 or the 9800 GTX + is less efficient and 9800GTX ... "V2" more expensive than in 4850!
