EVGA GeForce GTX 560 Ti 2Win Dual GPU Review

[Mungri]

C'mon this thread is getting insane. I understand some of you are trying to save face here, or you just don't know.

The 560ti 2win is vram limited.

Here is BF3 @ 1680x1050 "Ultra Preset" (nothing else tweaked) rush, canals, and my two 460se 1gb in SLI.

I ALT+TAB'ed out of the game as soon as the lag spikes started and took this screen cap.
Notice how the GPU utilization drops when the vram is allocated to the max 1000.



This is what causes the lag spikes. The GPU/s are starved!

My 460se's in SLI can run the game at ultra ~60fps until the vram is full, then its lag spike heaven

Sorry but no. Your system only has 4 Gb ram. Your lag spikes are occurring because excess Vram is being stored into the shared ram instead, which vastly reduces your amount of available system ram.

Those lag spikes can be eliminated in two ways:

- GPUs with 2 Gb Vram
- Upgrading your system ram to at least 8 Gb.

Users of 1 Gb GTX 560s in SLI do not report lag issues in BF3, Metro, or any other modern game with sufficient system ram for both normal ram use and shared ram (minimum of 8 Gb system ram, which can be had for <£30).

If you actually bothered to upgrade your system ram to 8 Gb (which is significantly cheaper than the current price premium on 2 Gb video cards), then your lag spikes would also be cured.

Yep if your planning on playing new (such as bf3) and/or future games at max (i.e. ultra) then 1gb SLI, or CF is a complete wast of money. You need cards with >1gb vram.

Only if you have less than 8 Gb system ram. With sufficient system ram you do not get lag spikes from Vram shortage, only a slight reduction to FPS due to shared ram being slower.
