Wanting to Up Grade My Mac Pro mid 2010

I have a mid-2010 Mac Pro and it came with builtin wireless. I would check to be sure that your Mac Pro doesn't have it before you add anything for wireless.

If you are having troubles running multiple Adobe programs, the amount of RAM you have sound too little if I read what you have correctly. I take you have 3 GB of RAM since you have 3 GB cards which is not enough for multiple Adobe programs.

24GB minimum for your needs.

You could even look for a GPU with 2GB or more, and even today a GTX 680 or above, or AMD 7979.

SSDs - can't say enough about them.

http://www.macperformanceguide.com has a lot of information for professional graphics and Adobe users.

3GB of RAM is far, far too little for what you are doing. As The hatter said, 24GB is a good amount of RAM for your needs. You don't mention how much hard drive space you have, but that should be considered. Adobe apps need lots of scratch-disk space. These two things are relatively inexpensive to fix. You may find that you don't need to mess with upgrading the graphics card if you take care of RAM and HD space.

I might recommend macrumors.com, where you will find plenty of upgrade enthusiasts. Be careful though, it can get addicting. I don't know if you realize just how much your machine can be upgraded, but let me recommend a decent setup for graphic design.

1) upgrade the processor to an Xeon X5690. This will increase your cores from 4 to 6, and will increase the GHz to 3.46 from 2.8

2) upgrade your hard drive. Lots of options are out there, but I installed an XP941 Samsung drive on a Lycom M.2 (NGFF) SSD to PCIe 3.0 x4 PCIe adapter, which has worked very nicely. A bit more expensive than a standard SSD, but makes the machine FLY

3) upgrade your RAM. I agree that 24 GB is a minimum for graphic design. More is basically better. Get 48 GB if you can (3*16 GB is a sweet spot for price/performance)

4) upgrade your graphics card. You didn't mention which programs you run. I agree with the hatter above that the GTX 680, AMD 7950, or the AMD 7970 (would need to get a modified card from MacVidCards for this) all provide excellent performance, and a significant step up from the 5770. You can get significantly faster cards than those mentioned, (GTX 980, Titan, etc) but whether the price is worth it really depends on what programs you use.

5) get a few big 3.5" spinning drives for internal data storage

Let me know if you have any questions.
