I have reaf seversl posts yhat make it sound like just flashing a jellybean rom wil do this. I know better than that but cannot find the definite answer. Will the cappy even handle jellybean? If not then what is the best possible set up as far as android version for rom choices and stability?

Quickie guide to installing ROMs.

1. Grab the desired ROM of choice. Cyanogenmod 10/Slimbean is a good start
2. Get the gapps for the ROM. http://goo.im/gapps/.
3. Get cyanogenmod7 from http://download.cyanogenmod.org/?device=captivatemtd
4. Get CWM here: http://www.semaphore.gr/kernels/Semaphore_2.5.0c.tar
5. Heimdall here: http://www.glassechidna.com.au/products/heimdall/. You don't need to install anything extra with 1.3.1
6. Copy the gapps, CM7 and your ROM of choice into the internal AND external SD card. Some rom comes with a kernel that don't play nice with either SD card, so both is better.

Install

7. Extract Heimdall, go into the driver folder, open Zadig.exe
8. Pull the battery of the phone, put it back in. Hold Volume Up + Volume Down and plug in the USB cable
9. Once Windows detect your phone, click on option -> List all device. Look for Gadget Serial Control, Samsung Composite Device or similar. If it look like your mouse/keyboard/webcam/other internal component, don't touch it. Click on Replace Driver, and wait for it to install.
10. Go back into the heimdall folder, hold shift, right click the folder and select open command prompt here.
11. Using 7zip/WinRAR, copy the content of the Semaphore_2.5.0c.tar file to the heimdall folder.
12. On the Command prompt, type:

heimdall flash --kernel zImage

13. Once your phone reboots, it should bootloop. No problem. Pull the battery, put it back in, hold volume up + volume down and press power until it turns on. You may need to do this a few time. It should boot into recovery mode.
14. Select install zip file from SD card -> Choose from Sd card -> the Cyanogenmod 7 file. Confirm with yes
15. It should reboot automatically, and bootloop. Do the pull battery trick from 13 to get back into recovery mode. Do 14 again. This time it shouldn't bootloop.
16. Go back to the main menu - Wipe Data/Factory Reset -> Reboot
17. Wait for it to boot.
18. Go back into recovery mode, and Wipe data/factory reset again. Install the ROM of your choice, along with the gapps. Newer ROM should ask you to flash it again to confirm. Do it.
19. Reboot
20. Enjoy

As for the GB vs ICS vs JB issue:

GB gives you the best performance. You don't have to loose your 3D performance to compensate for RAM. ICS is the best of both world. Slim ICS run (almost) as fast as GB, have the smexy Holo UI without compromising your 3D performance. JB give you the most features, but you'll have to give up your VRAM + 720p Video Recording/Playing(Devil kernel can give you back enough for 720p, but you still loose the VRAM).

ICS is actually not recommended around here due to the EU bug. It happened on so many devices so it really comes down to GB vs JB. JB has way more features while GB is a retro/stable OS.

Actually, JB have the bug as well(see the last 10 pages of the thread, 2-3 reports). At least IMO, the reason there are little reports for JB is:

1. Its been nearly 3 years, most people got a new phone through contract
2. The hardcore modders already got the EU bug, and thus is using JB
3. The remaining population stick with GB to prevent it from happening altogether\

The most likely cause for the bug is something in ICS/JB along with the age of our hardware.

Same false statements like in Development section.

BigMem = Taking from your VRAM. Less VRAM - Worse 3D performance. You can take less and still have 720p, but your 3D performance will suffer in comparison. Same as with the old 10mb hack for the Dream'/Sapphire.

Not exactly true. 3D performance is a function of graphics chip rendering speed and drivers optimization. Less RAM affects only the ability to store data. You may see some reduced performance in heavy 3D graphics, but Captivate with it's single core CPU is not a gaming device anyway. For general use there is no difference in performance. Android UI does not use 3D rendering by default.
