Dell Optiplex 755 Video card compatability

likhithchitneni,

The Optiplex 755 is getting on a bit, but there are more options to improve it than one might suspect. Checking Passmark Performance Test baselines, the highest rated system uses a Core2 Quad Q9650 - 4-cores and 3.0GHz, a Radeon HD 7750 , Samsung 840 SSD, 8GB RAM. This system rating = 2134, 2D=482, 3D=1872- quite amazing really. Of course, the parts would add up to quite a bit, the CPU will be between $80 and $120 . the highest rated dual core is the E8600 at 3.33GHz, with a CPU score of 2671 and costing about $35-50. You can buy an entire Optiplex 780 fwith an E8600 for $90-110. A quite highly rated system uses a Core2 Duo E6850 and Radeon HD 4850: Rating = 1418, 2D=479, 3D=1154 and the good news is the E6850 is $15-25. If you are not doing tasks that can use all the cores, I would think that having the 3.0 GHZ dual core would be a noticeable upgrade. A reasonably priced- $30-40- quad core is the Q6700 at 2.66GHz.

The highest 3D scores for the 755 include: GTX 750 Ti, Radeon 7750, GTX 650, Radeon 6750. A lot of the choices of GPU will depend on whcich form factor- case size you have. If you the very slim desktop that sits horizontilly the card will have be only as long as the PCIe slot, cuch as a GT440, though several of the newer cards are those quite short ones.

I'm all for getting older systems going well for little money. I was a given two systems recently, a Dell Precision 390 and Dimension E520 and spent $75 and $110 on used parts and made very noticeable improvements, the Precision 390 went from a system rating of 397 to 1458 and the E520 from 384 to 1220. Still, I suggest you look at you system, check it's value in the completed listing on Ebahh, add the amount you wouldn't mind spending on upgrades, plus another say $20-50 and see what the total will buy. If your current system is limited to 1GB of memory, it may be time to consider a change. If the total of your system plus upgrade budget is $150 or more, you have 100's or 1000's of choices. For example you can have an Optiplex 980 with a 3.33GHz dual core, modern i3 and faster memory in a roomy minitower case for $90-100 and room for a wider choice of GPU's:

> a completed listing for $81, only needing the operating system. If there is a COA, you can get a restore disk for $15-20 load the OS and use the COA number. this would need a GPU and perhaps RAM, but this could all be done within the $150. An Optiplex 390 with an i3-2120 has a CPU=4241 and an i3 system with a GeForce GTS 450 scored 1943 in 3D. the advantages of a modern CPU and faster (1066) memory.

As I say, I like to have the old systems going- they're far more useful than many pepl might think when upgraded properly, but it's also a good policy to see if one older system might be converted into a newer old system for the same cost.
