Worth upgrading my GTX460 SLI to HD7970? - Page 2

post #11 of 33
Yeah, it's going to be a big upgrade. GTX 580 is actually 20-30% slower than 7970. Not to mention 7970 can easily be overlocked high enough to gain extra 30% performance. I don't believe SLI GTX 460 can be close to 590. 1GB VRAM will be the main bottleneck. I'm also saving up for 7970.

Edit: Also wait for Ivy Bridge. Your AMD 955 @ 4.0GHz won't be much a noticeable bottleneck.

What are you guy's opinion on this?
AND!
Should I wait for Ivy bridge to come or get a 2500k =P ?

Honestly, get a nice P67/Z68 board and a 2500K. You'll 460's will shine with that kind of overclocking headroom and horsepower.

Then upgrade your GPU(s) and if you want/need the update, get Ivy.

1GB VRAM limitations really don't take into a effect until you hit 1200p+.

I use x2 470's and get amazing frames in Battlefield 3 @ 1080p with everything on Ultra with a some AA and x2 MSAA. Never drops below 85 frames, peaks at 140 frames at times. Plus, before you say anything else, I used to use a single 3GB 580 and my 470's out perform my 580 by a marginal difference. And to top off the shake, games like Battlefield 3 compensate for VRAM so even though the game uses over 1.2GB of VRAM, I still don't use my full VRAM off my cards.

OP should be investing in the motherboard and processor though, those 460's have a lot of potential and with them in SLI he doesn't "need" an upgrade. The 7970 purchase would be based on a "want".

In my opinion. I've been there, purchased this, that, and honestly, I wish I would have just stuck with my 400 series. Which I ended up trading my 580 for anyhow.

I currently have 1 7970 and 2 MSI GTX460 IG's in SLI. I say not "worth" it from a gaming point of view. I do understand just wanting to upgrade.

BF3, Metro 2033, Crysis and Crysis 2 uses all of my VRAM on 1080p. I get dips to 20-30fps during the intense fights in BF3. 1GB VRAM is not enough for some games.

Well, I don't with my 470s. Turn down your AA and such and I would put money you wont have that problem.

Yeah, the game will still use the VRAM but AA and MSAA are your VRAM hogs.

I don't even have AA and MSAA on in Crysis and BF3. Some people actually want to play with AA or MSAA.

i've had my 460's overclocked to 1ghz before and didn't see a difference in terms of fps between 1ghz and 840mhz. my rig bottlenecks hard at the cpu and/or everything else. the new rig im building in my signature is sitting, waiting for IB and a Z77 along with a 7990. but i'll probably use the 460's before grabbing the 7990 just to see from first hand experience how well the 460's can do in a non bottlenecked environment lol

Oh bty, OP
HD 7970 is a overclocking beast. That's my other main reason I want to get it. If you love overclocking and this card is right for you.

I would but reading all the posts, it seems that it'll bottleneck my CPU.

I'm currently window shopping my i5 setup
-Gigabyte UD5
-2500k

Total= $480(Amazon)

Ive read that Ivy can be used with a LGA 1155 mobo so hopefully this investment should be worth it.

I just really dont know how the heck am I gunna sell my 955+990fx mobo lols (<-- Not in the rep req)

I started a thread a couple days ago, wondering the same thing as the OP. Thank you! you gave a better answer than I have been able to come up with, I'm sticking with my 460's now.

Now what to put in the wife's rig.... Hey OP, I'll buy your 460's.
