Upgrade or Crossfire?

post #1 of 30
Thread Starter 
All right all you AMD fans. I have recently converted to an AMD GPU and I love it, I've been converting as many people as I can.

I want more performance out of my gaming rig, I'm stuck at the decision whether to go crossfire or upgrade my 270X for a 290X (possibly water cooled as they tend to get hot and noisy from my research). Either way is gonna cost me almost a similar price cause I will have to upgrade my PSU if I go crossfire.

My question is will I get more performance out of crossfire 2GB 270Xs or a single 290X? Also is there anything else I should consider about this upgrade?

My specs are:

i5 4670k @ 4.2Ghz
Asrock Z87 Pro 4
Gigabyte R9 270X OC
2x8GB Ripjaws X @ 2133Mhz
840 EVO 250GB with RAPID
Thermaltake 750w EVO Blue 2.0

Cooler Master N400 KNW2 Case
Cooler Master T4 Hyper CPU Cooler
5x 120mm Fans to keep **** cool

Temps normally sit at idle CPU= 35c - GPU= 31c
Temps at load (BF4 SP Ultra @ 60fps 1920x1080 slight fps drops maybe 50) CPU= 50c - GPU= 55/60c

Most will say upgrade. A single high performance GPU is better than multiple lesser ones, and you'll spare that other slot for a future crossfire setup.

I'd say upgrade to a 290, and buy a block for it. Should cost around the same as a stock 290x wink.gif

I have found performance increase going to a single r9 290 over a 6990 + 6970. Here is a link to firestrike extreme compare. http://www.3dmark.com/compare/fs/623018/fs/1851863

Thanks heaps for that guys, I was leaning towards the 290 but I had some doubts.

If you can help me out a little more what is the main differences between the 290 and 290X?
I do like to play around with overclocking even though I'm fairly new to it and this is my first PC that I have overclocked.

Also I live in Queensland Australia and those temps are what I achieved over summer so I doubt I would get to hot but I'd rather be sure cause 40c days are a bit of a worry when you don't have AC.

coming from a single 270X . . . the difference between the PRO and the X will not matter. both will be an upgrade. huge upgrade.

what i think would be a concern is your PSU. although it is 750W, the quality of the brand might not be up to snuff for a 290.

I wasn't worried about it running it but now I am. I thought I looked at reviews for all my parts but it seems I missed the PSU. I'll keep it and give it a go but I'll keep it in mind.

So when I googled reviews it seems they have a ripple in the 12v rail. Would this cause BSOD? When overclocking with the Asrock motherboard OC profiles it runs perfect on 4 or 4.2 but in 4.4/4.6/4.8ghz profiles it becomes increasingly unstable after those speeds. I thought it may have been the core as I have seen a few forums with people with similar stories, but I have seen people get 4.6 with ease and used the same settings. I have similar problems with overclocking the GPU but I really have been stabing in the dark with that cause I can't find any good info on overclocking them.

Thanks he actually helped me with a mates PC that was BSOD, he taught me a lot and not to believe the bronze/silver/gold rating system and to look into the OEM. Thanks for tip I'll message him now.
