I have a GTX295OC and I want to buy a HD5850 (and OC to 1000MHz core / 1200MHz ram) because I don’t want sli any more, a few games don’t have sli or in some games when the fps drop below 60 it is feel choppy compare to a single card (I mean 45fps feels smother on a single card compare to a dual card). Also the new GTX4xx are out and as usual nvidia will probably stop the proper driver support for the GTX295.

I will sell my GTX295 the same amount of money, as the HD5850 so is not going to cost me anything.
So it is a good idea to exchange my GTX295 for the HD5850 or I will regret it later?

imo, your going to regret it. Nvidia will 'not drop' support for their old cards. Dell is installing the GTX 260 in brand new gaming rigs right now. If you read launch reviews for the 5870, where in some cases the gtx 295 was used to compare in testing. The 295 is faster than a stock 5870 at 850mhz. The 5850 is about 10% slower clock for clock, ABOUT,imo. The o/c only scales so much, in part along with memory. Lot of IFS. At best its a side upgrade and maybe (i hate to use this word,) smoother experience !

(the average performance of many games)

The HD5850 is about 19% slower than the GTX295 so if I OC the HD5850 from 725core to 1000core(that is a huge OC 38% !!!) then the HD5850 will perform similar to a GTX295OC

IF you can OC it that much. the 5850 OC"s very well, but most OC's hit around 900ish from what ive seen. Ive only seen a few with 1k+.

If you o/c the 5850 that high, believe it or not you would use about the same power as the gtx 495. The 495 like the 5970 is basically underclocked, its at its sweet spot for power/efficiency. So is a stock 5850/5870, but o/c like our cpu's you start upping the wattage faster.

Got my HD5850 at 1000/1200 and its slightly faster than a stock HD5870, and a HD5870 with todays drivers is roughly as powerful as a GTX295. So it would be a side step rather than an up or downgrade.

Thats one set of results, and even if those, the o/c 5850 uses 75 watts more than stock.
They are also testing intel burn test at the same time.
Nothing is free.
edit: At that link, theres your answer, clocked at a 1000,the 5850 still loses to the 495 clocked at 576 in most games.

You are right, this is better than free. You can Ebay the GTX 295 for more than the cost of an HD5850 and you will gain DX11, use much less power and have no SLI scaling/compatibility issues. Considering the performance is very similar there is no reason not to do this.

gtx295 is better than 5850, but it doesn't support dx11..
anyways.. stay with 295 for now or get sapphire 5970 4gb

i would also agree, you would want to go higher then a 5850 otherwise you would be getting performance decreases, a few days ago i ran 3d mark vantage with my single gtx 275 with the new 257 beta drivers, and was getting just shy of 13000, on my gpu score. which is roughly or slightly less then a stock 5850, and mind you your 295 has got two of my 275 under the hood

and again i saw performance increases with the new drivers just as those with the new 4xx card did

a HD5850 @ 1000/1200 will perform like a GTX295, if you can sell the GTX295 for the same price as a new 5850 then go for it, then later down the road you can get another for performance past a HD5970.

If money isn't an issue then just buy a 5970.

Thats if your card can get to those speeds. A 5870 and 5970 can probably hit 1000mhz easily but a 5850 might not.

Yeah true, I think most will do 1000Core with a voltage adjustment, but some may not.

I have 2 5850s at the moment and they're awesome, OCed at stock volts to 875/1200. However, while I still had just one I worked on OCing it for a few days and my absolute max seemed to top out at 985/1200 with 1.225V (stock volts is 1.08V). However there's a thread here at Toms about FurMark benchmark results and I scored slightly higher than another guy who had his at 1000/1220 for some reason. Could have been my CPU OC.

Anyway, I don't think getting the 5850 after having a GTX295 is worth it. Really, the best part of DX11 is tesslation which is a marginal improvement to looks, and only in certain games anyway. I'd say if you really want to get an ATI go for a 5870 instead as that would actually give you an upgrade.

Off Topic.

You beat me in Furmark even when my 5850 was at 1080/1230 and my core i7 920 at 4Ghz

Buying a HD5870 is pointless because a HD5850(OC 900MHz) perform better. Also a HD5870(OC 1000MHz) is about 5% faster than HD5850( OC 1000MHz).

Probably I am going to buy a HD5850 and if I don’t like it I will return it back.

That card would probably be fine but the Asus card has a nicer cooler which is worth the extra $20 imo when going for an extreme overclock with voltage increases. Also Biostar just started making video cards a few months ago. Their motherboards are decent but personally I would rather go with a more established brand when spending $300+
