I recommend the 2nd pc for the following reasons:
1. The i7 has a higher clockspeed than the X5680. For Solidworks, clockspeed is more important than the number of cores.
2. 1600 MHz memory instead of 1066MHz. Much faster.
3. An SSD is much faster than a HHD.
4. The K4000 graphics card is much faster than the FX4800
I agree with the choice of number 2 system particularly since the first system is "used". There is some comfort in buying a workstation from a recognized manufacturer, but without a warantee, your home-build sounds good.
Ok thanks for the advice!
In the end I think that I will go with a 4790K instead (a bit faster for a couple of euros more), and I might end up having to get a K2000 as the K4000 is kind of outa the budget at the momment. But I saw in the benchmarks it will probably be fast enough for what I want to do.
Any other things that you might reccomend?
Well, if you are on a tight budget, you can save $300-$400 by doing this:
Get 16GB memory instead of 32GB
Get a 256GB SSD instead of 512GB
Get a K2000 or a W5000 instead of a K4000
Well I think im going with a 256GB SSD from Samsung (evo line) and a 2TB Hybrid drive from Segate.
Also the memmory is quite cheap so I might stick with the 32MB (I can get it for 300Euros) depends on the mobo I go for and the PSU. I just dont know what memmory to go for. The 4790K can only use memmory with a 1600mhz speed according to the intel website, but what happens if I get one at 2400mhz? And is the speed better or the CAS latency?
I am opting for the K2000 it looks plenty powerful for what I need and maybe in the future I can upgrade to a 2nd hand K4000 or K5000 when the prices come down.
Lastly any sugestions on the mobo? I want something I can OC and I had an ASUS ROG before on a 4770K and I quite liked that.
The K in the CPU part number means that it's unlocked for overclocking.
This means that with a few tweaks you can get the 4790K up to 4.6-4.7GHz.
Here's a review of the 4790K - http://www.tomshardware.co.uk/core-i7-4790k-devils-canyon-overclock-performance,review-32968-2.html
Yes I was planning on OC in the future with a custom water setup, i have read the 4790K ha better thermal dissipation so that is good!.
Any advice on a good OC mobo and memmory?
I saw that intel also has some warranty options that allow you to OC your chip and keep a warranty, so maybe I will look into that and start OC before the warranty period is over
Also silly question would a K600 + a gaming GPU be better than a single K2000?
My experience is that most people get very little performance increase from buying the higher end video cards. But you are looking at a low end card versus a mid-range card and you might actually get some usable benefit. I don't have any experience with either, but the older Quadro 600 works just fine for me.
The benefit from a low end professional card and a gaming card would be the better gaming experience using the gaming card and an adequate engineering experience using the professional card. I doubt that you will get any benefit in engineering from the gaming card, nor any benefit in gaming from the professional card. But you should get some advice from someone who knows, not from me.
