Hi, I'm looking at some 4k TV's now that they're in the Semi-Affordable bracket, Right now I have a i5-2500k OC @4.4 (can go to 4.8) but for 24/7 use and not needing such a high OC I lowered it.

I'm Looking at a pair of Titans, or 780ti's which should provide good GPU for 4k from what I've read, however I'm not sure if the CPU I have now will cause any problems or not. I also have a i7 4770k here just waiting for a board, but I get better performance in games with the oc Sandy Bridge than the Haswell. Any input would be appreciated as I've scoured Google and haven't found any 4k gaming benchmarks with a 2500k.

Here's some interesting comparisons on a 780Ti between 1080p, 1440, and 2160p: http://www.guru3d.com/articles_pages/evga_geforce_gtx_780_ti_sc_acx_superclock_review,22.html

Note the difference in frame rates of: 97FPS vs 70FPS vs 35FPS

Gaming at 2560x1440, if the HDTV supports it, is a good compromise and really I doubt you could see the difference between 1440p and 2160p. And even a 2nd card won't get you from 35FPS to 70FPS!!

You'll want a low-latency gaming input as well so preferably an HDMI v2 compatible, dedicated gaming input.

I have a 2560x1440 monitor and game mostly at 1920x1080.

Most games look almost EXACTLY the same with maybe some of the HUD text being very slightly fuzzy in comparison but that's it.

It makes a big difference for small text but then that would be unviewable on a large screen as you'd be too far away.

Cards:
Titans are a waste of money. You can beat one with a $500 EVGA 780 967MHz model. They're meant for people who need Double Precision.

A single EVGA 780Ti with ACX cooling is my advice and game at 1920x1080.

HDTV:
I don't think it's a good idea to buy a 4K HDTV yet. They're still working out the kinks nor is HDMI v2 even finalized yet. Give it a year or two and you'll get something for a lot less money.

CPU and 4K benchmarks:
Since you already know the 2500K performs better when overclocked than a stock Haswell CPU then it stands to reason there won't be a huge difference.

It sounds like you plan to use the 2500K in the living room and Haswell elsewhere. That's fine though the Haswell setup would be quieter with the same CPU and performance level.

So if this is the case my final advise is thus:
1) lightly overclock the 2500K
2) Get a single GTX780Ti
3) game at 1920x1080

Again, seriously, the game textures aren't going to look any better. Anti-Aliasing solves the jaggies performance wise better than running a natively higher resolution and the ONLY, again, ONLY advantage is the HUD text.

*There's also talk of licensing G-SYNC to television manufacturers including Sony (Sony could produce a G-Sync HDTV and license for the PS4 if NVidia allows). If so, a G-SYNC HDTV would be really awesome with an NVidia PC.
