R9 270X Crossfire, 2GB vs 4GB?

Sup guys.

I'm looking at (from a cost perspective) either a single 770GTX, a single R9 280X or crossfire R9 270X's.

I have read a few threads where people recommend buying the best single card you can, so that there is scope for future improvement. Frankly I'm not bothered about that in the slightest and just want the best performance now.

I was thinking if I bought AMD I could at least get my rig mining 24/7 (when I'm not playing any games) to recoup some costs, and understand Crossfire 270X's should be quicker than a solo 280X.

So the question is which cards. On OC I see there's an offer on the MSI 4GB Gaming cards for the same price as the Asus (£168).

When you're running crossfire, surely that means the GPUs have 8GB total to play with doesn't it ?? Which for a 1080 monitor is overkill, max I'll be running is 2x 1080 monitors, a single 1440 monitor or one of those 25:9 aspect monitors).

Which ones should I get?
 
770 or 280X in my opinion. I'd never recommend a crossfire setup over single GPU, unless you just want to benchmark.

If you have an i7 2600k or better, id go with 270X crossfire as it will overpower and outperform both the 280X and 770 easily. If you have a lesser cpu id go with a 280X/770. If the 4gb cards don't cost much extra, id go with them as well but if its a lot of extra outlay i wouldn't bother and would stick with 2gb per card.

Nope, the memory is mirrored in crossfire, so you'd have 4 gb effective for all cards to use.

270 x fire will be quicker yeah, but crossfire compatibility and scaling isn't always great, it's game dependent.
 
Cool thanks for the input.

I don't play anything at the moment, used to play BF3 and will most likely give BF4 a go. Other than that.. It's mostly

The MSI 270X 4GB is on offer with OCUK at the moment. So 2x of them delivered is about £343.

My CPU is an i3 550 so I expect the cards to be completely bottlenecked by the CPU. I'm not too worried about that as I'll give the motherboard and CPU a refresh later this year, and it will get me playing HoN and L4D at least. Later this year I can look at refreshing my motherboard and get a nice new i5 or i7.

I'm not too worried about that as I'll give the motherboard and CPU a refresh later this year, but I want a GPU (or pair of them) that will be good for a few years and this seems like a decent enough way to get that. (And if they pay for themselves by mining then great!)

Fair enough. Upgrade that cpu asap though, cos an i3 will be a big bottleneck. i7 minimum recommended. :)

Ordered!

I know they're nothing spectacular compared to some of the cards people post but I am excited!

Its not far off 7950 Boost stock crossfire, which is nice and powerful and is up there with a 780TI, assuming scaling is good. Take a look at this thread when you get your new gpu's and your i7.
 
Thanks very much dude!

Yeah that sounds like more than enough GPU power, I used to have a HiS 7950 which was a wicked card, I'd buy them again if they sold them new or they were reasonable prices on eBay. But in my experience it's better to play it safe and buy new with warranty for computer parts.

3 year warranty on these cards is a nice piece of mind.
