Sorry I started off the thread with the sole thought of just upgrading the GPU but towards the end of the post it did raise the question to me if maybe it is time to sell and upgrade. Also thank you so much for the replies. It helped reconfirm some of what I had been thinking. With that being said, I'll put out my scenario with my two options.
So my overall set up actually is what has been holding me back from just going out and getting a nMP. Not trying to boost saying "money is just no option to me" but it plays no real factor into my final decision other than me thinking I spend too much money on something that might be an overkill for my real uses. So no don't just say ditch the old and buy the new for 9,500 lol. And No I do not edit using FCP or Adobe everyday. I do a full media package for a high school football team so off season I do heavily edit I'd say two weekends out of the month and during the season every weekend and some during the week. I list a write up of what I need and use my set up for at the bottom because it will most likely be long and not everyone will care to read it. But since my real job takes #1 priority and most all of my time, having a computer that is technically beyond my needs is important to me because of time.
Curent set up is
2009 Mac Pro 4.1, Quad Core 2.66, 32gb of ram, back to the stock GT120 after I sold the GTX670 FTW. I was running both cards so I had an extra PCI slot and kept the boot screen.
I run a 256 SSD off a PCI 1x card since the bays do not support Sata III (R/W is is just under 400). It is used for OSX and Apps only.
Bay 1 has another 250GB SSD in that use as a general scratch drive,
Bay 2 has a 600GB 10k RPM WD Raptor drive that runs Windows 8.1 via bootcamp (No partitions with Mac OSX) I have thought about moving the bootcamp drive to the SSD and using raptor as scratch. I run some Adobe in Windows and have the a few games like Call of Duty, I might play once in a blue moon.
Bays 3 and 4 have WD Black 1TBs in a Raid 0 (Almost 300 R/W I think)
The last PCI slot I use has a raid controller with four external esata III ports with all four ports being used to run two separate HD enclosures with 4x1TB WD Blacks in total in a Raid 5.
Was running a USB 3.0 in one of the PCI slots over having the GT120 in there since I do have two 3TB WD backup drives for everything (along with a 2TB Time Capsule) but since speed really was not as important to me on the backup drive plus those HDs are too slow to take advance of USB 3.0 I put the GT120 back in.
That is the bulk of it minus a small NAS server that is used to connect to music libraries and print server etc.
So with that being said, it seems much much easier to go spend the $600ish on a GTX 680 but I have known the issues with Nivdia lacking in the OpenGL support and it is very easy to tell that since CS5 to CC to has slowed even more and crashing is starting to slowly happen here and there. I picked up FCP X only after Mavericks was released because it was middle of the season and Adobe Premiere Pro/After Effects and Lightroom crashed upon attempting to launch. Since there was no ETA on the fix I picked up FCP X (which I love and does run a WAY faster than Adobe CC does now but still trending slower than it was. I had a few FCPX trials before I went with Adobe CS5, I knew I get FCPX down the road but needed the full Adobe packet to start bc I also use Light room and Dreamweaver and Prelude is perfect for indexing the game footage for me. Which leads me into my next issue. I will be keeping all game footage (which is three different cameras total) so I will have a storage crisis soon. I would have bought big HDs but I already had a few and the Raid set up was more important for editing purposes. I read off one of the raids and write to the other. Original footage is on a external HD or my MacBook Pro until I have time to index it, back it up and finish project so I'm sure not to lose anything. So there is pretty much my situation. Moving to a nMP will require a few adjustments for the raid controller, unless I bite the bullet and get a thunderbolt now and maybe an expansion chassis for the PCI cards. And I have the whole bootcamp HD, and two SSDs that will need a home. I never dreamed I would be this involved so I was unprepared and made due as we went.
Long Story - I'll just save for later. It was entirely to long and off topic for now.
