Picking a GPU for new build

post #1 of 7
Thread Starter 
Alright, so for the last year and a half or so I have been creeping these forums waiting to put together a custom pc, and I'm an getting ready to finally order some damn parts rolleyes.gif

I have come up with a final parts list for the main core of the pc, I am not looking for any other options in that department, what I can't decide on is a gpu. I had originally (back when I first joined the forum) been looking only at Nvidia, because it seemed to be leading the pack in folding, but in the last month or so I have been coming back to your neck of the woods and finding out that ATI seems to have caught up. Which threw a monkey wrench into my plans, and for the last week I have been looking up guides for ati folding and sorting through possible gpus.


SO, looking for some advice on a couple of options I have on the table.


Core Parts: http://pcpartpicker.com/p/1gdbq (I dropped the 7970 in there as a place holder)

^---standard 3770k build, silverstone psu, muskhin ram and msata ssd, asus maximus V gene mobo. the plan is to watercool everything in a 600T case with a phyoba 400mm rad in the front bay section, psu will be for main components only, secondary psu will run all fans and pumps, etc
^---Uses for this build will probably be 80% folding, remainder being light gaming (FTL, Endless Space, Star Conflict) and random web browsing, possibly video rendering if my wife decides to get into youtube like she has been talking about for the last month
^---Also, any parts will be ordered from NCIX.ca and picked up locally at a storefront, meaning there will be no shipping cost.


GPU Options

1. single 690s + EK waterblocks, purchaseable at $750 used, waterblocks come in around $150, approx $1000 with shipping (all parts need shipping)

2. single 7970 + ek wb, gpu $450, wb $120, approx 600 with shipping(waterblock)

3. dual 760 + ek wb, gpu $250, wb $110, approx 800 with shipping(waterblocks) (secondary option, just run single for now, so approx $400 shipped)


Which GPU option presents the best option for the most efficient folding?

RIght now I am leaning towards Option 2. Specifically the MSI Twin Frozr OC BE, because it is a reference pcb and can be converted to single slot. I saw the Diamond 7970 for sale on their website, but for the cost difference I don't see a reason not to get a black pcb, plus there will be shipping.

My original plan was to break the bank and go dual 690s, but looking at the entire price tag I realized I would be better served putting that money elsewhere. When my budget came by and slapped me in the face with that realization I immediately withdrew my position and resigned myself to a single 760. I got a bit bolder with things when I realized ATI had gotten back in the game, and decided to consider a 7970, with the option of a second in the future if some extra money trickled into the gpu jar I will be putting on top of my dresser. thumb.gif

Help? Please and thank you! biggrin.gif

I would go with something like this instead, Haswell Rig. You have to be more spesific with your budget. My opinion is to get the latest tech available when you build a new pc, unless you are money limited.

Thanks for the input, but core components won't change.

Reason being that I purchased mips motherboard blocks back in december for the maximus V gene, so I am dedicated to the Gene board as of right now. Went with the msata because I am trying to run as minimalist as possible within the 600t, ram was picked to complement the boards overclocking potential, psu was picked for 100% modular as well as brand loyalty LOL

Right now I am just looking for input on gpu choices.

Budget for the card is flexible, no more then $1000 all in with the waterblock. If I can stay close to the 500/600 dollar mark, like with the 7970, my wallet would prefer it. which is why I even put the sinlge 760 on the table

With this build also consider that there is only 2 pci slots, so if I do completely populate the board, would dual 780s (if I went that way) perform better then dual 690s?

Here is a cheap one http://www.overclock.net/t/1401771/3x-7970s-with-ek-water-blocks-two-sold-one-card-left-330/0_20

Used one in my TC rig http://www.overclock.net/t/1374609/amd-sempron-145-folding/0_20 gets me around 120-125 k ppd on the 7970 alone.

I would go single gtx 780. It offers about 10% less performance than a Titan at only $650. It will make anywhere between 125k and 175k ppd depending on the WU and the overclock, which is higher than any other option you listed (besides the 690 which is the best but also much more expensive). Actually, Anubis is selling his 690 for $800 so if you do want one, I would contact him. A 780 though is a sweet spot between performance and price for folding so that is what I would go with if I were you because you can always add more in the future when the upgrade bug hits tongue.gif

Option 2 with the 7970 sounds like your best bet. All your games are pretty easy on the GPU, so the 7970 will kill them and pretty much any other game for that matter, plus the 7970 folds awesome now. I got my 7970 for $309 after rebate. If you ever need more GPU power, you can Xfire later on. The 7970 is the most bang for your buck.


(BTW I have SLi 760s on my gaming rig).

If you look around you can easily find a 7970 for ~300 bucks, for instance a XFX one here for $340 http://www.newegg.com/Product/Product.aspx?Item=N82E16814150665 , the 7970 is where the best PPD/$ is at this point in my opinion, and with your budget is where I would be looking at.
