GTX 770 and 1440p
Hi guys. I'm looking to buy the Asus Swift 2560x1440 monitor with 144Hz refresh rate. The only problem I have is my current video card, MSI GTX 770 4GB. I know it's not gonna handle my games very well even if I disable AA on 1440p since I play some demanding games like Battlefield 4, Bioschock infinite, Farcry 3, Hitman: Absolution, Crysis 3, and Skyrim with about 60 mods give or take. I have 2 questions. First question is the problem I have with my GPU I want to get to run my games at 1440p 90FPS+. I could get another GTX 770 4GB for $400 and SLI, It's the cheaper solution but it will just be a waste of money in the near future since there is no room for upgrading. On top of that, some games don't support SLI and I've heard of how annoying temperature spikes and frame sluttering can get. The more expensive solution is to get a GTX 780ti. It's currently $650 on newegg and I would think that this card can handle 1440p with no problems at all. Any ideas on which one I should go for? The second question is about anti-aliasing on 1440p. I have heard people say 1440p looks fine with no AA at all, but some people argues that 1440p still need 2x MSAA. Now, I'm not a jaggie extremist, where a single bit of jagged edge will blind me; however, I do like a smoothed out game with minimum jaggies. I sit about 3 and half feet away from my monitor and I ususally use 2x MSAA (1080p) but sometime 4x MSAA (1020p) if it's not a demanding game, I barely notice jaggies unless i put my eyes 1 inch away from my monitor. Would I be able to get by with no AA on 1440p or do I still need 2x MSAA? Some light on this subject would be appreciated, thanks!
Since you already have a 4 GB GTX 770, you could just SLI them. However, a performance increase in every game is not guaranteed. If SLI is supported though, you should be able to enjoy your 144 Hz monitor with 2x MSAA. Anti-aliasing is both VRAM and bandwidth dependent, so even if your 4 GB VRAM is enough, the 256-bit bus won't, despite the very high memory clocks on the GTX 770. Alternatively, you could always opt for cheaper post processing-based AA options like FXAA and TXAA. But personally I'd stick with just 2x MSAA. FXAA and TXAA will blur the entire image, making your 2560x1440 image less sharper, and thus less enjoyable. As you've said, the returns on higher AA settings at higher resolutions like 1440p are low and not apparent. 2x MSAA should be enough.
