Which setup for BF4: 7970 or 560ti x2 in SLI

post #1 of 9
Thread Starter 
Currently I'm running two 560GTX-Ti Twin Frozr II/OC
Other specs: i5 2500k overclocked to 3.9ghz
8gb (4x2g) Geil 1600mhz black dragon
120gb OCZ vertex 4
120gb Strontium Hawk
800w psu
Couple of green/blue drives but all games live on the strontium

At the moment I get 70+ fps running BF3 on High, 1920x1080 but it chuggs a bit on Ultra. Not sure if its a CPU bottleneck or I'm expecting too much from my gfx.
Either way I've been meaning to upgrade for BF4. From all the videos that EA have released about the game they have said that ATI cards will run the game better and the game is currently tested on high end ATI cards.
I don't know if it's just EA talking out of their ass but has made my decision lean more towards ATI.
That and 560ti drivers have been a joke for SLI.

I was leaning towards a 7970 but can't find any SOLID comparisons between them.
Would a 7970 be a decent upgrade?
If so which 7970 with a limit of $500 au?

Cheers guys cheers.gif

It might be hard to find up to date information on how your 560ti's in SLI compare with current drivers to a 7970 with current drivers, however based on these 2 reviews done by techpowerup which suggest the 560ti SLI has an average improvement of 47% over a single 560ti at 1200p, it can be estimated that a stock 7970 would be around 15% faster then your 560ti SLI setup.

Factor in OC'ing and you might be looking at a 30%+ performance increase, but even then tbh I don't think it's worth upgrading to unless your 560ti's only have 1gb vram. If I were you I'd hold on to them and wait until the 9950 and 9970 come out (I hear they might even be bundled with BF4) and then decide on whether or not you still need to upgrade. And your 2500k @ 3.9Ghz won't be bottlenecking your 560ti's in SLI so there's no need to worry about that.

are they 1GB or 2GB? I own 2GB in SLI, and coupled with 2600k @4.6GHz, BF3 on Ultra/no AA in 64 man @1920x1080 stays above 30FPS

OP i advise you to wait for HD 9950 launch next month and then pick up a HD 9950 depending on whether its priced at 500 AUD. there is also an expectation that HD 9950 is coming bundled with HD 9900 cards. now is not the best time to buy a graphics card especially if you can spend so much money.

btw even a HD 7950 boost is faster than GTX 560 Ti SLI

http://www.techpowerup.com/reviews/HIS/HD_7950_X2_Boost/28.html

1920 x 1200

GTX 560 Ti - 59
HD 7950 iceq x2 (950 mhz) - 100 (59 x 1.7 = 100.3)
HD 7970 Ghz - 115

so on average HD 7950 boost is 70% faster than GTX 560 Ti. SLI scaling in best cases is 80% but on average across many games is 60%. also a single GPU is smoother and has better frametimes than multi GPU. HD 7950 overclocks to 1100 - 1150 mhz and easily matches HD 7970 Ghz.

http://www.legionhardware.com/articles_pages/his_7970_iceq_xsup2_ghz_edition_7950_iceq_xsup2_boost_clock,13.html

MSI HD 7950 TF3 boost edition for AUD 300 is a very good deal. 960 mhz boost clocks. good cooler and unlocked voltage.

As someone who owned 560 Ti SLI (2GB models), I think your estimate is pretty spot on. In my experience they performed virtually identically to my GTX 670. That said, I'm assuming OP has 1GB models, which may be a bit of a hindrance even at 1080p now.

@OP: If you're on a tight budget, a 7970 could be a nice investment. Their price/performance is excellent, and it would be a moderate upgrade, not only for the raw horsepower but the added VRAM. BUT with the next gen cards launching in a couple of weeks I'd probably wait it out and see what they bring to the table.

op, if you can find a cheaper 7950 and oc your cpu to at least 4.5GHz (which you will have to do with the 7970 anyway), then that will work for BF3.

i maxed BF3 MP 64 (1080 ULTRA and 4MSAA) with the 7950 at stock with my i7 at 4.5 HT on and off. the 7950 at only 1100/1500 will be faster than a stock 7970.

you can wait for the next gen cards but they will be a bit more expensive.

Cheers guys, you are all absolute lords
Sadly i only have 1gb cards. I'm gonna try crank up my cpu today and make sure it doesn't die.

But yeah it looks like i'll wait, didnt know the new cards are only a few weeks away. I definitely want 1 card though, might upgrade later as i've never tried crossfire only sli which has been buggy. But yeah don't exactly want to spend 1000$ on gfx. Either way i'll definitely wait a few weeks. The plan is to upgrade for bf4, beta comes out in a few weeks so i guess i'll see how my setup performs with the beta.

Overclocked cpu to 4.22
Holy mother of christ it runs so much better. I really never thought the cpu would be the bottleneck.
Get like 70+ on ultra max everything now ***
