Best graphics card for 400W PSu? (Silver power SP-SS400)

[eilif]

So i want to get a replacement for the GT 430 1 GB.

Heres my system:
AMD Athlon x2 250 @ 3.0 GHz ( can VERY easily be overclocked! )
4 GB of RAM
Gainward GT 430 1 GB ddr3
500 GB HDD
Windows 7 32 bit (supposed to be 64 but i screwed up)

So yah.
The GPU doesnt quite satisfy my demands, so i'd like to get a better card

I play loads of games..
GTA IV, CoD4, Black Ops, Crysis and that kind of stuff.
But the GT 430 just doesnt seem to do the job good enough

So my question is what is the best GPU i can get for under 250$?
The PSU is a Silver power SP-SS400 400W.

Amp ratings:
17A @ the +12V1
17A @ the +12V2

Do you have a number under both rails it would be the combined wattage rating. Without knowing just how good teh PSU is i would say a safe bet would be a 5750 or a 5770 if the PSU is up to it. Either will be a good size increase.

It has a maximum combined wattage of 360W

That means it has a combined +12v rating of 30 Amps which is plenty to run a 5770. I assume it has a single 6 pin Pcie power cable ?
On the subject of the OS what do you mean you made a mistake ?
Take a look at the 5770 review and see if it fits your needs. There are other options if you want to stay Nvidia, but we would need to keep it to cards that only need a single Power cable. http://www.techpowerup.com/reviews/HIS/HD_5770/28.html

Well i can only use 3.25 of my 4 GB's of RAM
I accidentally bought the 32 bit version, i was supposed to get the 64 bit.

But to be honest, i prefer NVIDIA over ATi.
I think NVIDIA's drivers are so much more user friendly.
Although ATi is quite a bit cheaper.

But will the 5770 be able to handle the listed games?
I have no problems with running medium resolutions, but if it is possible, i would prefer the native resolution of my monitor (1920x1080)

Will it be able to run CoD4, MW2 and Black Ops on High/max settings?

And what about Crysis?

Thanks

Regarding the OS again, when i bought mine it came with both 32 and 64 bit disc's. So did you get a deal or was it part of teh PC bungle ?

Anyway the HD 6850 would be a decent option considering the resolution you are running at.

I ordered it myself..
okay, thanks

Isn't the max. combined current output also an important factor. At the moment I've got big performance problems with my 560ti and I'm not sure if the 34A of my PSU might be the reason for poor performance. I heard that 38A are at least required for a 560ti, is that true?!?

To be honest i couldn't tell you without either seeing the spec plate of the PSU or knowing the make and brand myself.
The combined current is very important ind is why some PSU's that sound a good deal end up being rubbish.

you should be able to run a 6850 from that psu if it can really pull off those amp ratings. cant find any proper reviews of that psu unfortunately.

It's a Seasonic S12 on the inside, I wouldn't be afraid of running a 6850 with it.
