I don't see how a different CPU is going to increase BF3 performance at all. Going to a 6970 from a 5870 for BF3 isn't a bad choice. About 10 more FPS plus he'll be able to use more AA. I just can't recommend going CrossFire anymore.
He is in the UK, a 2GB 6970 will run him about £280. That is a lot of dough for 10 FPS.

Seen a few used 5870s for £130 on Ebay "buy it now". I'll go CF, save £150 whilst getting the same or better performance as the 6970.

But that brings up the question; Will the low-end 800W 2nd tier supply stand up to run 2 5870's?

800w is enough. I don't have enough power connectors :(, So new psu.
Power connectors isnt a big deal, you can buy molex to 6-pin adaptors for like £2 if needed.

The issue is, is your psu of quality, what brand is it. What is the amp per rail like?

If need be, you could still get a good Corsair, Thermaltake, Antec, XFX etc PSU, about 52A - 60A for about £60-70 and you'll be within budget to go CF.

One of them rarely heard of makes, if I got xfire I would defiantly upgrade the psu. If I got the hd 6970 I would consider still upgrading it. Any idea what I could sell a used xfx 5870 for?

Ebay, they are selling for about £100-120 in auction. Or about £130-150 in "buy it now".

If you can sell your 5870 that would also be a good move. Use the rest of the money to fund a 6970 like erocker suggested. Although you'd need to to meet the difference to the tune of about £150 for essentially a glorified sidegrade. Maybe you should wait for the 7xxx before opening your wallet.

Yea I have 70% of the money for a 6970 at the moment, with a Acer Aspire one that I need to sell along with the 5870 I can sell. Early in this thread erocker said the 2gb of VRAM would be better than 1gb, I'm Gunna skip the 7 series, get an oc'ed 6series (or a 5970?) and wait for the 8xxx to get a big leap in performance.

I'm not sure how big your screen is, but for most resolutions 1GBs is just about enough for BF3. Although 2GBs would futureproof you for a bigger screen (higher resolution) + future games. If you get the 6970, yes the 2GB does get my general recommendation.

Dont be blind, you don't know the 7xxx series performs until official benchmarks are out, for all we know the 8xxx series might be slower. The 5xxx series was faster than the 6xxx series (hence your upgrade dilemma)

So the 5970 would be the fastest choice out of all cards? Does the 5970 act like xfire since its 2 cards in 1 and mirror 1gb VRAM?

I havent read through all of the posts so forgive me if im chiming in here and have lost the plot... The original poster linked a 6970 and appeared to be happy with the price... that card will be perfect... go for it :)

The fastest out of the mentioned is the 5870 CF

5870 CF > 5850 CF > 5970 > 6970 > 6870.

Although the 6970 and 5970 perform similar enough to be almost the same.

It's 1 PCB board so the ram isn't mirrored, its a full 2GBs.

Edit:

5850 CF? With a 6970 I would at least have a 1000mhz core and a high pushed mem clock. I suppose two 6970 would own all?
The clock speed makes no difference. Comparing clock speeds especially of two different generations of card will not give you a measurement of performance. Yes CF 6970 would own all (not because of cockspeed alone)

BTW. There is another choice of card. The 6990, costs £550-650. Because of its price tag I didn't bother mentioning it earlier.

if youre caught between an ATI HD5XXX series card/s or 6XXX series card it only makes sense to go for the latest model (6XXX).... it will cost less than a dual card or crossfire older model solution, 6970 will play BF3 in 1080p easily with room to spare and run cooler and use less power than the older 5XXX series.

It's late. Bed time.

Some interesting benchmarks http://www.anandtech.com/bench/Product/292?vs=303
Agreed, Stayed up to see the extremely helpfulness from everyone.

I'm gonna forget about the 5 series then, if they are cooler then overclock is generally better.

6970's CF will own any game out at max settings with no trouble whatsoever.
I might be able to fork out for xfire the chances are slim, i will have to wait and see.



Thanks for your help everyone, its helped me a hell of a lot, its 3am where I am and I need some sleep. Cheers

I compared the 5870CF and 6970, I think with an overclock the 6970 would close the gap
A 6970 will come nowhere close to 5870 cf IMO. Video cards overclock by a few %, nothing huge. And those benches contain games that may well be cpu-bound, whereas BF3 is, in almost all cases, gpu-bound.

BTW your original 700w PSU just might do it, if it's a good brand. Some people exaggerate the power draw.

Wow, what a load of BS. 5970 and 6970 somewhere similar? Whathow? What are you smoking? The 5970 is MUCH FASTER than the 6970, even comparing them is ridiculous. And then again a 5850cf is FASTER than a 5970? :twitch:

Here's a bit of REAL AND RELEVANT INFORMATION so that the OP is not completely blindsided by your misguided BS:

Want my opinion tommy? Lower the res you play at and wait it out for HD7k's.
My opinion is to keep the res he is playing it.....Keep FSAA OFF, turn down Shadows to High or even Medium, and get the all important 60 FPS that he is yearning for. And if that dont cut it then try dialing down a few more settings in BF3. In BF3 in particular, turning settings down results in remarkable increases in performance for a very hard to notice downgrade in picture quality.

Spending around 300 quid on that card is just stupid as it offers only a marginal performance increase over the 5870.

Wait it out for the HD7K's and see how much the 7950 is retailing for and what its performance, overclockability and unlockability is.

When is the 7 series released?
