Hi, I'm a computer science major who will be focusing on high level computations in the future, as well as an avid gamer. I have around a $2500 budget to build a computer that fits my needs for the high level computations, but I have a few questions. For one, I read somewhere on Tom's that the 7970s are better at computations than 670s/680s, is this true? Secondly, I'm looking to run either dual 7970s or dual 670/680s, but from what I've read microstuttering is a huge problem with dual 7970s. The mobo I plan on getting will have one more slot to fit a third gfx card in, but I won't be getting a third one until around another year from now. I will have three monitors, each 1920x1080 Asus VH242H 23.6", and I'd like to be able to game across all three during my free time however from what I've heard microstuttering is even worse across three monitors. Thanks for any answers
I plan on having:
Core i7-3770k or Core i5-3570k liquid cooled
2x 7970/670/680 depending on prices and answers
1050W power supply
Antec 1100 case
16 GB DDR3-2133 G.Skill RipjawsX
2-3TB hard drive.
as of right now, any suggestions on what else could be used is appreciated.
The total for this off the beaten path build is $2615.89 and before you keel over let me explain why.
The center of this build is the 3930k Sandy Bridge-E cpu which has six cores and hyperthreading so that you have a total of 12 cores available and massive amounts of L3 cache (12MB). It would seem to be the answer to the high level computations and gaming that you are intending the Pc to be used for. The two GTX 670's will compete with any combination of video cards and when a third is added that will put it over the top and you would have a video solution that would be better than any.
If this is not your cup of tea then no big deal the build can be reworked to your satisfaction. I just thought I would throw this out there to see what you think.
this is a bit less than the build inzone suggested. it is about as good though. the nh-d14 will completely destroy the intel water cooler but then you will have to live up to the color of the fans
for games, going with 670s is a better choice since it uses less power than the 670 and usually costs less. for compute power, a 7970 can beat a 690 so i opted for the 7970. you can always go with 2 evga ftw 670s
This is what I've come up with so far. Using a Sandy Bridge-E processor never occurred to me, what benefits would it have for computing? And for gaming, is it = to a 3770k? Also, I have 2 monitors right now, and the build I did included the third one. I think I will go with the 7970s as long as I think micro stuttering won't be an issue. I also just figured out I'm taking fewer hours than I thought, so my budget may go up enough to get what you have picked out along with a monitor if I'm lucky.
As you can see by these benchmarks two 670's win thier share of the battles and this is just in gaming so another question that needs answering is does the cuda cores add an assist to what you intend to do with the high level of compute.
The Sandy Bridge -E is a six core cpu with hyperthreading and a L3 cache of 12 MB and for the compute part you will have to find out if more cores is a better thing or not. The 3770k is a quad core with hyperthreading and that means there is 8 cores available with a L3 cache of 8MB. The thing is to know if the extra cores would be a benefit or not.
I currently have a 980x which is a 6 core cpu and if and when I upgrade it will be to something compatable to that , so right now it would be the 3960x or the 3930k.
I would most likely be using OpenCL, which the GeForce cards don't support, sadly. I know the difference between the two processors, I think my real question is are there any benchmarks anywhere that show the differences with multiple graphic cards across multiple screens that compare the 2600k/3770k to the 3930k?
This is what I have come up with for an x79 build. It is slightly more expensive than what has been seen before but it also has a monitor included in the price. Suggestions off of that?
I will say that is your happy with what you have listed then the only thing left to do is buy it and put it together. I think it looks very good and will serve you well.
I do think that with an expensive build you should have gone with the top brand of psu in the SeaSonic and if your going to be adding a third video card Me personally would be choosing a 1200w psu. I had three GTX 580's at one time before I just sold one , and I had the 1200w psu. Maybe it was more than I needed but I wanted to be sure of having enough power and some extra. The reason I sold one of the 580's is because I'm planning on upgrading to newer cards.
