Hello all,
I have a new DDR4 build I completed a few months ago. The only older component was my GTX 770 2GB that I swapped from my previous pc. Although this computer functions beautifully, I'm still having trouble with some of the newest games, I'm guessing due to my aged graphics card. I cannot run full graphics on games like GTA V etc. I've never dealt with SLI, and cards are expensive after all the money I've spent on this build so......

First, is it reasonable for me to purchase another identical GTX 770 2GB to run in SLI with what I already have, or buy one (1) recently released card?

If I buy another 770 to run SLI, does it have to be 2GB or can I have two 770s running SLI with different memory capacities?

Is it possible to run a recently released Nvidia card SLI with my older 770?

Basically what's the best option for upgrading graphics capabilities, including my older 770 or starting fresh?

I just filled out my build in my profile and I'm not sure if that is visible when I post this or not. If it's not visible I will go back and edit this post.

Thanks for any help!

Yes, the 2GB is most likely your problem. For 1080 resolution and games that are a few years old, a 770 GTX is fine. However, the latest games use more than 2GB at 1080. It would be a better investment to buy a card with more VRAM.

Just curious, is this build solely for gaming?

No. For SLI to work, you must have two cards with the same VRAM. You cannot mix VRAM. Nothing else really matters for SLI. If one card is slower, the faster card automatically slows down. VRAM doesn't add either. The two cards act as one so you'll still have 2GB when SLI'ing.

It might not be a bad idea to upgrade GPUs.

Thanks for the link! I apologize for not reading ahead, but replies on Tom's are usually so fast I figured it'd be a better route to take! haha

So I guess my next question is...... Would two 770s at only 2GB in SLI render similar performance to a single recently released card, or would a 900 series with more memory do the job for new releases (keeping within a fairly similar price range)? I'm guessing the "2GB" is the problem, but I'd like to hear from someone more knowledgeable.....

Thanks again!

I do a lot of gaming, but I also have a home studio and do quite a bit of live band recording. A graphics card upgrade would mostly be for gaming right now, although I am versed in and have thought about also using this build for CAD work with software like Master Cam and/or Solid Works (machining technologies stuff). I went with a DDR4 build because I had been saving up for it for a while, and I wanted to build something that would last me well into the future.
