hey guys, looking for a bit of help really, im wanting to know which would be the better option of these 4 at 1280x1024, as my current GPU has started artifacting.

radeon hd 4890 1gb
radeon hd 5770 1gb
gtx 260 896mb
9800 gx2 1gb

ive had a look around and performance wise it looks to be 4890, but im not sure if dx11 should play a major part in my decision,

PC specs are:

Athlon ii x 2 250 (oc'd to 3.4ghz, but will be upgrading to quad core soonish)
2gb ddr3 1333 (again, upgrading to 8gb 1600)
600W Evo Labs 80+ ATX Power Supply
win7 64bit
asus m4n68T-M LE mobo
geforce 7025 / nforce 630a chipset

current gpu - palit radeon hd 4870 sonic dual edition 1gb - have had to turn it right down in CCC to compensate for the artifacting.

5770 have the same performance of 4870(16ROP/800shaders) but 5770 is much more efficient(5770 need 107w/4870 need 160w) and 5770 support DX 11 which it will allow you to enable some effects like1 tessellation and 2depth of field(exclusive for DX 11 graphics cards)

the quickest graphics card is 9800GX2 but its also the least efficient(9800 GX2 need 300w)which also mean a lot of heat and noise to deal with, then 4890 is 15% slower than 9800GX2 then GTX 260 which have the same performance of 4870.
4890 is the best DX 10 choice

i would rather buy new but cant afford to at the moment, tbh i was hoping to get it in to CeX for exchange value and pick one of these up with the exchange from my 4870 + a lil bit of money. until i can save up a couple of hundred to get a decent one lol.

In that case, I would recommend the 5770. It's going to pull similar performance to a 4890.

Copy your current gpu bios with this...(and flash it with your modded rbe bios after)

Change the hd-4870's fan profile so that the card runs cooler at idle, and the max temp is lower. DON'T MESS WITH THE OTHER CARD'S SETTINGS. ONLY CHANGE THE FAN SETTINGS ON THE FAN/TEMP CHART ON THE SECOND PAGE OF THE EDITOR.
This should fix the artifacting.

maybe the ddr-5 memory is weak, try running the card's memory at 800mhz after you fix the fan profile. It should fix the card without hurting fps too much.

Neither.

If you are going to be spending money, look at the new mid-range AMD cards.

I think the 7770 would be a terrific choice for you.

I never noticed the power supply before.

600W Evo Labs 80+ ATX Power Supply is a cheap generic power supply..

It will artifact too if the 12 volt rail is weak, and those hd-4870's do use up to 180watts under full load.

Buy a new power supply like a antec or corsair, or ocz, seasonic, SILVERSTONE

Don't buy off brand power supplies they often don't put out what they claim, have lots of ripple that damages stuff, and fail.

It could be your power supply and not your card.

It doesn't hurt anyway to buy a decent power supply before you put expensive cards and boards into your system.

ah, i thought that was an ok one when i bought it lol. thought thats what the 80+ meant :D

It is a efficiency rating.

I think there is a good chance it is not your card that is broken.

I have had bad luck with off brand power supplies in systems i have repaired for others. I had good luck with antec, corsair, and ocz. I heard from others that seasonic and silverstone power supplies are good too.

You can ask others in this thread about that. I have to go out and wont be back for a while.

Also changing the fan temp profile was a common fix for hd-4870 cards, they were set to run hot at 80C which proved to be too hot for the memory chips.
Ask some others about this too.. Your card is probably fine and just showing some age and can be repaired with software.
