Geocidal :
I want good multicore performance but I ralize single ore performance is important as well. Which of these has better single core performance?
CPU boss says that E5-2643 has better single core perfomance yet it has a lower clock speed.
Would the E5-2643 be better for gaming in spite of it's lower clock speed?
Gecoidal,
Xeon X5690:

On Passmark: AV. CPU score: 9270 Rating = No. 102
The highest CPU score for a single Xeon X5690 is 10482 (Custom ASUS P658X Prem / GTX 560 / 16GB RAM / OCZ Vertex 4)
Xeon E5-2643:
http://ark.intel.com/products/64587/Intel-Xeon-Processor-E5-2643-10M-Cache-3_30-GHz-8_00-GTs-Intel-QPI
On Passmark: On Passmark: AV. CPU score: 8474 Rating = No. 139
The highest CPU score for a single Xeon E5-2643 is 8735 (Dell Precision T5600 / Quadro NVS 510 / 16GB RAM / PERC H310)
So, by the numbers, the elderly X5690 is the winner. However, the situation is not simple. The E5- is hyperthreading and has a 51.2 GB/S memory bandwidth as compared to the X5690 32 GB/S bandwidth. It's possible that these factors and with optimal motherboard and GPU(s)- how many X58 m/b support SLI?, on programs that can use high performance SSD's, that the Xeon E5-2543 can take advantage of the bandwidth, SLI, and M.2 to be experientially- feel- faster. The highest system rating for a single X5690 system is 3817 and the highest rated single E5-2643 system is 4420. There's those pesky numbers again telling a slightly different story,..
It's a complicated equation to say neatly that one would be better for gaming as a modern E5 / X99 motherboard will have features and performance- for example M.2 , bandwidth for the GPU, and SATa controller that no X5690 / X58 board could match. If you use the X5690, find a good LSI or Adaptec SAS /SATA RAID controller for a 6GB/s disk subsystems. Taking all the factors into account, with high end components, the E5-2643
might seem faster and have a higher FPS rate. Note that for gaming, using either CPU, ECC RAM will be slower.
I would say from experience with both Xeon E5-16XX and Xeon X5XXX that the Xeon X56XX series was one of the best previous Xeon series perfectly usable today.

Optional irrelevant content: The X5670 2.93 / 3.33 for some reason seems to perform amazingly well (8229 No. 149 and only about $120 on Ebahh) . Given it's low cost, 6-cores, ability to use two and ultra-reliability, the X5670 is excellent for Matlab systems that can sit in the corner and do flight dynamics or fold proteins for weeks on end. The higher clock speed X56XX make very good visualization systems and rendering engines.]
It may be that you have these two CPU's around, but I would say the best cost /performance Xeon for gaming might be the E5-1620 v2 (4-core @ 3.7 /3.9 GHz) . The first two cores under load will run at 3.9Ghz and with a 59.7GB/s bandwidth and RAM at a native 1866 (Passmark: 9503 No. 91). The E5-1620 v3 (9581 No.81) is 3.5 /3.6 GHz with a 68GB/S b/w and 2133 DDR4 but quite a bit more money will be spent and the clock speed is a bit less.
Interesting question. May I ask what are your plans?
