Im building a brand new gaming computer and I've pretty much made a decision on what i want. Im looking at an Asus Crosshair V Formula Z and an AMD FX 9370 which i will oc, but i have read forums that in sli PCIe2.0 can limit you and bottleneck, I'm looking at 3 Gigabyte Windforce GTX 770 OC 2GB cards and i was wondering if i would be bottlenecked a lot. I have a decision on all my parts this is just my concern, thank you in advance! :) 

More about : amd gtx 770 sli

The only problem I see is the the 770's. You will be limited by having only 2GB VRAM. More and more games are using more than 2 and even 3GB of VRAM. Battlefield 4 and Titanfall, most notably. I switched from 2 770's to 2 780's and I've been happy ever since. Consistently seeing frames in BF4 between 150-200 on Ultra+ settings. I say Ultra+, because I add in a lot of extra tweaks through drivers and Inspector. All while being enjoyed of a 144 Hz gaming monitor. You can't beat it.

If you are going to spend that much money on video cards, since SLI doesn't scale well (with 3 and 4 card setups in most cases) and AMD processors are pretty bad at gaming . . . Why not get dual cards that have more RAM or more powerful cards and get an i7-4770k instead. It would be a much more consistent and better performing machine.

Are you going to be running on a 4k screen or triple monitors or something?

Thanks for the tips on VRAM my build is based around BF4 so thanks

Im either going to be running 3 monitors or I'm future proofing some what because i don't have all that much money, i choose AMD because 1. they are cheaper 2.you can get very very similar performance like I'm going with the AMD FX 9370 which is same thing just with 8 cores 3. I'm basing my build around BF4 and 8 cores is now optimised for BF4 4. i don't see anything bad about AMD and gaming

Yeah, BF4 works pretty well on AMD, unless you want to play multiplayer and then suddenly it's running slower than most i5's since more CPU power is needed. You may want to switch to AMD video cards so that you can run mantle if you are getting and AMD processor, since the goals for mantle are to reduce the amount of work that slow processors need to do to keep frame rates flowing.

i have never seen this before ill do a bit of research thanks. I don't like AMD graphics cards they get hot and loud, I'm also looking for something with 8 cores so i can game and listen to music and browse the internet and record and so forth for being a you tuber, also i want 8 cores so that once games use more than 4 cores i will continue to have the same performance once 4 cores is out dated.

Snag an FX-8350 and some fancy cooling. The Asus Crosshair V Formula Z is one damn nice motherboard.

PCIe Gen2 x16/x16 dual cards will be just dandy. Scaling beyond 2 video cards is simply not worth the cost --- you will be better served using 2 GTX 780s in SLI or 2 R9 290s in CrossFire.

If you already own a single GTX770 -- sell it and put the cash toward your new parts.

edit: The non-reference coolers on the R9 290s run cooler and more quiet than their competitors.

I had realised that but i was thinking that 3 midish high cards for less will get more performance but PCIe2.0 was my only problem and I'm also looking to save money but i want the same or more performance than an i7 and in a lot of test the 8350 came up the same and 9370 is better than an 8350 so the 9370 will be perfect while still costing less than an i7. Thanks for the tips i will try and find something but what do people think about a 780 Ti Classified and a 750 Ti in Physx?

Just as an example:

http://pclab.pl/zdjecia/artykuly/chaostheory/2013/10/bf...

If you notice even the 4670k not overclocked beats the 8350 in their test even when the 8350 is running at 5Ghz . . . 2 780's with a 4770k would be a far more reasonable, consistent, and efficient gaming rig than 3 770's and a 9370.

There is actually a really great review of SLI scaling over at http://www.neoseeker.com/resourcelink.html?rid=232807 . . . in some cases three cards don't even go faster than 2 cards at all. It's certainly not a case of 3 cards being 50% faster than 2 cards as you would expect in a perfect scaling scenario.

ok ill take that into consideration but they don't have a 9370 OC'd or 9590 OC'd,they would be close to the top and the price for them are amazing on amazon much cheap than intel thats why I'm going AMD

Presumably your gaming resolution will push the video subsystem more than your CPU.

You will have to snag cooling for the FX-9370, anyway. Save the $30-$50 with the FX-8350, buy some nice cooling, and you will be pushing FX-9370 clocks.

The 780ti is a great card for around $700 ... in the States the R9 290s are finally back down to $400. In Crossfire they should beat up on the 780ti.

Not sure what to tell you about the Physx (it's not something I really base purchasing decisions on ... )

I already have a liquid cooling system so alls good and i just found a reference model of the GTX 780 for under $500 on amazon so i will highly consider getting 2 of them
