jonah0037,
In my view, the technology is one or two generations behind that which can be effectively and economically upgraded. Upgrading an older system has very similar costs- obsolete CPU's and RAM are surprisingly similar. For the price of the higher performing Core2 Quad there are LGA1366 with far better perofrmance and that are using DDR3-1333 RAM instead of DDR2- 667.
My idea is to sell all the Optiplex 760's and buy one of these:
Dell Precision T7500 Xeon X5667 3.06GHz Quad Core HT 4GB 160GB DVD-RW FX3800 1GB > sold for $200
http://www.ebay.com/itm/Dell-Precision-T7500-Xeon-X5667-3-06GHz-Quad-Core-HT-4GB-160GB-DVD-RW-FX3800-1GB-/121817724823?hash=item1c5ce6f797%3Ag%3AxuoAAOSwlV9WS7UE&nma=true&si=wMzpYFm%252FGJDQS2ljqhnMZ8ec%252BsQ%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557
The Dell Precision T7500 is server build quality, can use two CPU's up to 6-cores, 192GB of DDR3-1333 ECC registered and has 4 drive bays and an 1100W power supply. The X5677 is a 4-core @ 3.06 /3.46Ghz. with an Average Passmark CPU score of 7046. By adding a CPU / RAM /Fan riser (about $60) you can add a second X5677 (about $60) and the CPU score is
11698. On Passmark, the highest CPU score for an Optiplex 760 is
4602 using a Core2 Quad Q9650. Becuase the Q9650 is the festest Core2 Quad, there is a premium price on them and these appear to average bout $70- they cost more than the X5677.
Then, to the above system, add a 250GB SSD and one to three mechanical drives. The disk system of the T7500 is SATAII 3GB/s so, a PERC H310 RAID controller can convert it to 6GB/s. I added a PERC H310- ($60) to a PRecision T5500 and the disk score improved from 1940 to 2694. The GPU is not critical for a server and for example the Quadro FX 3800 in the system above would be perfect- a very good 2D score. Using the T7500 mentioned at $200:
System:_________________$200
CPU Riser_______________ $60
2nd X5677_______________ $60
48 GB RAM______________ $140
PERC H310______________$60
Samsung 850 Evo 250GB___ $90
2X WD Black 1TB__________$160
_______________________________
_________________
TOTAL = $770
You would then have an 8-core / 16 thread @ 3.06 /3.46Ghz, 48GB, 250GB SSD/2TB 6GB/s system.
It's difficult to say what your Optiplex 760's are worth, but it appears they average perhaps about $70 each. So, if you budget is limited, it possible to buy the $200 system as above and add 12GB RAM ($30), the SSD ($90) and one HD (WD Blue 1TB $60) for a total of $350- equal to about 5X Optiplex.
I've had seven used Precisions over the last seven years- still have four and all with perfect reliability.
