6870x2 vs 560ti OC? 600W PSU with i5-760

post #1 of 36
Thread Starter 
Yeah I know it may seem like an easy choice but my current setup may limit any Crossfire setup:

Core i5-760
600W OCZ ModXTreme PSU
4GB Corsair XMS RAM
P7P55D mobo

I just in fact ordered a 560ti Hawk. My mobo doesn't support SLI but does support Crossfire and 2x6870 would run me about 340 euros (price of a 570 or 6970) vs 200 for the 560. But the performance gain seems substantial.

I'd expect to be able to run BF BC2 with 16xAA (instead of 8xAA currently with my 460 768MB OCed to 850Mhz).

So it'd not be a small extra investment, but it'd be more future proof it seems.

So, as a concencus: worth it?

Thanks

Okay, well let me see here.

I wouldn't get a GTX 560 Ti, as it's merely an overclocked GTX 460.

What I would do, is get an HD 6950 or two. I got mine for 180$ off eBay. That's less than 150 Euros, I believe.

As for your PSU, I have the ModXtreme 780w, and even though some strict people in the PSU forum will tell you that it's not Tier 1, I would certainly recommend it.

Normally, I'd say 650w+ for HD 6900 Crossfire, but that's always with a large margain of error.

#1 a 560Ti is not just an overclocked 460. Why is basic disinformation so frequently spread on an enthusiast website?

http://www.anandtech.com/show/4135/

Quote:
GTX 560 Ti (GF114), in a nutshell, is a complete video card using the GF104 design; it is to GTX 460 what GTX 580 was to GTX 480. With the GTX 460 we saw NVIDIA disable some functional units and limit the clockspeeds, but for GTX 560 Ti they’re going all out.

GF110/GTX 580, GF114/GTX 560 Ti will be a fully enabled part: all 384 CUDA Cores, 64 texture units, 8 Polymorph Engines, 32 ROPs, 512KB L2 cache, 4x64bit memory controllers are present, accounted for, and functional. Thus compared to GTX 460 1GB in particular, GTX 560 Ti immediately has more shading, texturing, and geometry performance than its predecessor, with roughly a 14% advantage over a similarly clocked GTX 460 1GB.
#2 What's wrong with the ModXStream? I'm running a 2500k and an OC'd Asus 560Ti off one. No power issues so far.

#3 If you're just worried about BFBC2 and not BF3, then the Ti is more than capable of churning out hefty frame rates with full features enabled (though why you'd care about 16x vs 8x is beyond me - I cant tell a lick of difference). However, if you're looking for immediate performance for a game like BF3 (though the Ti runs the beta better than 60 fps, usually 80+, at 1680x1050 @ high/2xAA), then there's no denying 6870 xfire is a very affordable powerhouse. If you're not considering running SLI in the future with the Ti, I'd probably go that route.

Oops I did forgot to mention I use and game with a 1920x1080 resolution.

I've never tried 16xAA since well... can't run it with my 768mb 460. If there isn't even that much difference though I'm guessing I'll be fine with the 560ti for the following reasons:

Any reviews/benchmarks of the 478mb shows a barely playable BFBC2 performance. However with my OCed slightly I easily reach an average of 40fps with 8xAA and 16xAF. So I'm expecting (hoping!) the 560ti will be able to reach the same kind of framerates on BF3.

Yeah, I know how irratating it can be so see misinformation being written.

But I am not incorrect. The GTX 580 is, basically, just an overclocked GTX 480.

Things the GTX 580/G560 Ti have over their predecessors:

1.) Better core - runs cooler, overclocks higher.
2.) One cluster of SPs unlocked - 384 SPs on the GTX 560 Ti and 512 SPs on the GTX 580.

Now, if they were both priced well, I'd recommend them for sure.

But as we all know, they're havily over-priced, to the point where not picking up an unlock-able HD 6950 instead is simply foolish, or a GTX 480 for that matter, which can be had for as low as 200$ on eBay.

I didn't say anything was wrong with it, no need to get defensive about things I didn't say.

I said that the knit-pickers over the PSU forum would say it's not top-tier.

Now why would you tell someone to go GTX 560 Ti SLi instead of HD 6950 Crossfire for a lower price?

Tsk tsk tsk.

I'm a bit insulted that you listened to him.

If you're interested in 16xAA, you can do no wrong with the HD 6950 2GB.

Agreed. More cores and higher speeds do make the 560 Ti better than the 460. The non-Ti 560 is the same as the 460, only with higher speeds.

That PSU is actually on the Recommended OCN PSU list, so yea, i'd trust it.

Agreed as well. MY SLI'd 450's (roughly same performance as a 560 Ti) can handle even BF3, and have handled BF2 with ease. I can't tell a difference between 4xAA and 8xAA, so it's a bit beyond me why you want 16xAA.

A single 6950 should behave even better than a 560 Ti. If you're still keen on Xfiring 6870's, that PSU would not be enough. According to this guide, to Xfire those cards (and allow to OC CPU and a bit of GPU) you need a 650w PSU, so you also need to upgrade.

If you're going to get a 560 I think you'd be best off gettingthe EVGA 560 Ti 2GB version, I've been looking at them myself.

Thank you, that's what I was saying.

But the 650w is with a large margain of error, like I said, so I would think it would be okay.

I am kind of feeling invisible here.

If you want a 2GB GTX 560 Ti.. get an HD 6950.

It's the same price, has better performance, and 2GB of vRAM off the bat (no special addition necessary).
