ITS NOT HOLYWAR! So keep your personal opinions about either of the companies to yourself please.

Few months ago my old pc died and I built myself low price pc without GPU.
I choose Intel core i3, 4gb ram, 500gb hd and seasonic 430w PUS.
The future tough was to buy GPU later when Ill get more money. So future is here:) Im planning to buy a GPU.

My main use of the GPU will be gaming as well as game developing (using DirectX, maybe later in future OpenGL as well).
What would you suggest to go for? Nvidia or AMD/ATI? I know amd/ati have (had?) some problems with OpenGL. Is this critical enough to consider Nvidia? (Im planning to buy card with DX11 support, and seems like amd/ati offeres the best for price-value in compare to nvidia gtx4xx [I could wait for nvidia gtx4xx for mid-end/low-end users]).
I never had experince with amd/ati and always been nvidia fan, but amd/ati seems now as good cost-values GPUs also considers the pretty lame PSU I have (430W and not willing to change now).

Thanks.

AMD OpenGL drivers are now better than it used to be in the past. I have a Radeon HD4850 and never had big problems with it. Since money seem to be a problem for you I would consider buying the card with the better cost/value ratio. I think NVIDIA have better development tools through.

Those days are solidly in the past. AMD/ATI's OpenGL drivers have been on-par with NVidia's for some time now.

AMD/ATI's performance/watt and performance/dollar is unbeatable at the moment. NVidia's high-end parts are pretty nice, but as you mentioned, they don't have anything in the mid-range on the market yet, so AMD has that slot all tied up with a ribbon.

Depending on your budget, I would suggest buying either the Radeon 5770 (on the upper end of the mid-range), or the Radeon 5850 (middle of the high-end range) - though you might need a better PSU for the 5850.

You can buy a 5770 for around $160, and thus far it has played everything I throw at it (apart from Crysis [wink]) in highest settings, at 1920x1080 resolution, with anti-aliasing.

Thanks for your reply!
Money is not problems (however there are rational limit I can spent on GPU and GTX480 is not rational), the problem is the PSU I got (stupid me :( should have invset a bit more to get more Watt).

More comments welcomed!

Thanks! I was thinging about hd5770 as well!

What about linux support? Nvidia has almost always been FAR superior to ATI in that regard...has that changed at all?

I think ATI have probably improved in that regard, with more regular driver releases etc., but I'm not a regular Linux user so I couldn't say for certain. The last time I tried ATI's driver on Linux (about 2 years ago) it wasn't a happy experience to say the least...

Nvidia also support other *nix platforms such as FreeBSD which ATI do not, so I guess they are still ahead in this area.

My feeling is that NVIDIA's developer tools have always been vastly superior. On the other hand, it's quite a bit easier to get a hold of an ATI DX11 card than an NV one.

ati is kinda good for price/performance however as you want to do game developing i recommend nvidia.
-nvidia's gpu profiling tool works better (well couldn't get ATI's running in 2 days work).
-Also if you're using old techniques nvidia supports those better so that really improves development speed (/wink ati's vertex texture fetch which it does support but you can use it 0 times on "old" cards)

i personally have 3 ati's(1old, 1mobile, 1new) because i want to run into problems to see which nice techniques i cant use.

I think that is more a function of the poor documentation - it works fine for me, though it did take a while to figure out.

Note that this is a double edged sword - nvidia's glsl compiler Is much more permissive of non-standard code. A lot of shaders written for NVidia cards are just plain wrong, and thus cause compatibility problems.

Buy the slowest or second slowest card which matches your desired capabilities.
This way other users are less likely to experience a downgraded experience if they try your game.
FWIW Even slow cards today (except onboard gfx) absolutely scream
