New board or new gpu?

post #1 of 22
Thread Starter 
So I have a older 775 system on a MSI g31 board that I'm using as a 24/7 dedicated folder(which would be my only folder over the summer), was wondering in terms of ppd and power usage if it would be better to get a new board, like a P5Q-SE and OC or get a new graphics card(I'm thinking a GTS 450 or equivalent kepler card when available). Essentially, I want to pull more points than what I currently do using the same or less amount of power.

Between the cpu and gpu(q9400 at stock and 9800GTX at 800/1000/1998) it pulls ~11k-14k ppd drawing roughly 420watts from the wall(I'm guessing) on a Thermaltake TR2-700watt(80+ bronze rated).
Had a ECS P43t board before and I know the cpu can do at least 3.4Ghz(the max I got on that board), don't remember what volts that was on tho, but managed comfortable temps on the stock cooler.

Thoughts?

Thanks

(Would add I'm looking at spending no more than ~$300)

In terms of a new board you probably wont see that much extra PPD. However if you also bought a board and newer CPU you would see a huge gain for probably less power draw. 2 460s+2500k draws roughly 500watts for around 40-60k PPD. Although the GPUs are not as efficient as CPUs are points per watt wise. If you dont have the money for a new CPU+board than getting a GPU will probably get you more points

Generally SMP is king in PPD/W. Your guess of 420W is probably not too far off, but maybe a little high I guess. I've got a X6@1.47V and a GTX460@1.087V folding together pulling ~450W from the wall with a FSP Aurum 700W (gold) in between.

I'm not sure how a C2Q perform, but I would guess it's close to a PHII X4. I have a X4@3G that pulls ~150W and brings me 7-9k PPD on most units. A 450 swings between 8-10k, maybe up to 11-12k on good ones, and draws about 200W. A 450 is probably gonna cost less to buy than a decent 775 board these days (might not, as I don't really know your prices).

Once they (Stanford+Nvidia) has worked out an optimized core for Kepler, that's probably gonna be a good bet for GPU folding. But we don't know how much the low end cards gonna cost.

I wouldn't upgrade the board for that CPU, I've been considering this myself with the aforementioned X4 to clock higher but I don't think it will be worth it. There is quite a jump in terms of money if you wanna get a 24/7 CPU folder though, and as you're looking to lower the heat/power I would go for a SB K-series, 150-180W for a 2500K and 25-30k on normal SMP, 200-250W for a 2600K and 35-42k but then you'd need a new board, RAM and CPU which would cost considerably more than a 560Ti/460.

At this point in time, depending on budget, for a add-in GPU I'd look for a 560Ti (15-21k) or a 460 768MB (11-16k) (both of which are more power efficient than a 450) and maybe underclock/undervolt your CPU to keep power draw down.

Going with a new build entirely would be a bit out of budget atm - decent board and 2500k would probably be about ~$600 after shipping and duty importing myself, more buying locally (board and chip in sig system cost $1k back in august)

450 = ~$250 landed from ebay
P5Q SE= $175

Hmm, think I'll probably see how the prices go on SB and P67 boards after Ivy releases.
Can a decently clocked 2500k still manage bigadv/hugeadv units?

Sleepy Hollow Drive? NO WAY!

Sorry.. i was curious.. googled your long/lat.

a 2500k can manage bigadv but it really needs to be a dedicated folding rig preferable running in native linux. No one knows how long they will be able to complete the WUs as Stanford has talked about shortening the deadlines for a while. Cant tell you if they have done that yet though. You really need to have a decent i7 to complete them now in my opinion although I am sure others will disagree. I know there are currently a few team competition folders doing bigadv on 2500ks

^^Yep

Might as well go for gold then I guess. I'll just wait and see what happens with Ivy overclocking/SB pricing.

That time is now unfortunately. The new Bigadv Wu is out and the end of 690X wu's is in sight.

It's not advisable to attempt to build or purchase a 1p (single processor) Bigadv rig at this time.

I have been looking into building a 4p for work and folding but, board; single 12 or 16 core chip(ebay prices), and 4-8Gb ram is about $2000 after duty not including shipping, and then there's the issue of powering it. Between it paying for itself and power usage, not quite in that position atm.

Bummer, well I know a 2600k can do upwards of 30k-40kppd on regular smp, I think that would still be a good bet in the meantime, plus it'll only cost me about $32 a month to run with a decent overclock.

A 4p like mine (check my sig) only costs $1300-1500 USD and produces 220k on the new bigadv. It should consume no more than 450watts.
