760 sli related questions

[echobok]

Hi everyone,

I am currently considering getting two 760's to SLI and have a few doubts.

- For LGA 1150 it appears two cards take 8 lanes each as opposed to one taking 16, does this affect performance in anyway? Is it even possible to get both to have 16 lanes each?
- Is a 600 W PSU more than adequate?
- If I SLI both with PCIe 2.0 instead of 3.0 will it affect performance? That is should I even bother upgrading my i5 - 2500k to a i5 - 2670k.
- Is it worth paying more for the 4GB cards as opposed to 2GB cards?

Thanks in advance. Any general related advice is appreciated and apologies if these question have been answered before. If they have I don't mind reading the posts.

2. A 600 W PSU is what's recommended for SLIing 760s
4. No games use more then 2GB Vram (Exception being Crysis 3 used 2.2 with everything maxed inlucding the types of aa) and the 760 isn't fast enough to use all of the 4GB of Vram. A 4GB 760 is nothing more then a gimmick.

well, even if it does affect, it won't be more than 5% overall power maybe a lot less. Its possible to get 2 16x slot but you need the highest end motherboard with 4 pci express slot not really worth it. I have my gpu hooked to the 8x slot since my 16x slot is damaged and I notice to performance drop at all.

As long as its a quality 600w, it should be okay but you are pushing it to its limit nonetheless

Again it would make a difference but within 5% margin. Very little difference almost negligible. You may consider keeping your 2500k for now since its still one of the best cpus.

I would recommend 4gb over 2gb only because you are going sli. You would have enough horse power to beef up higher resolution and use more vram in the future games and the last thing you'd want is vram bottleneck. gtx760 may not be considered fast enough to use 4gb, but the gtx760 in sli is

On average how long will this benefit of getting more vram for sli last? If its not past three - four years, I'll probably just build a new rig is why.

It depends if games do evolve graphically much faster then they have been (start using a lot more Vram then now, something I doubt) in 3-4 years and if you plan on playing on extreme resolutions

the new consoles are hitting the market very soon it may change the way games are coded. Also there are couple of games that already utilises around 2.2gb vram maxed at 1080p.

Maybe I should have mentioned this, but I was planning on getting two 1440p monitors. Is it more of an incentive to get the 4GB 760s now?

Not really, the new console are both based on a x86 architecture and are weaker then a current "gen" PC.

they both have high amount vrams still. Ps4 comes with 8gb for a reason.

yes I would have recommended 4gb even for 1080p. now its a no brainer

The Xbox One is compared to a a higher cloked 7790 and comes with 8GB DDR3 of system memory while the PS4 is compared to a 7870 and has custom made 8GB of GDDR5 system memory.

8gb of its DDR5 is usable as vram as well. Meaning the console would use up to 4gb of vram in games. The new 'coding' may allow a hd7870 calibre gpu to use substantially more vram.

Either way console games are optimized for their respective GPUs. Non-exclusives will be coded and optimized for the "lowest common denominator" (The Xbox One) before being moved to the PS4s platform The PS4's GDDR5 ram is just suppose to be faster then the current DDR3 standard. It might also be used by the PS4s GPU and easily could but Sony hasn't explained why they are using custom RAM.

apparently the custom ddr5 makes it easier for the developers to write games for ps4 as opposed to the xbox one

Something only PS4 exclusives will take advantage from.
