VRAM and system ram are totally independent of each other. (you won't find any GDDR2 cards anymore, anyway)
The only issue you have is not the version/specification of the RAM you have, but the amount. Here's why... When you add a discrete gfx card, Win sets aside a video buffer in system memory relative to the amount of VRAM the card has. With your tiny amount of system RAM, today's gfx cards with 2GB, 4GB, and more of VRAM will mean Win will eat up a large chunk of your 2GB of system RAM. So unless you increase your system memory to at least 4GB, you will considerably slow down your system when you add a GTX 1050 Ti and possibly cause it to crash.
Thanks man, i understand it now. That means i have to upgrade my system memory.
Can you suggest a better brand for GPU's like GT 610,630.? They suits for me? Doesn't they?
Those are really slow cards, not really suitable for gaming. The lowest card I'd recommend for your system would be the GT 730 2GB
DDR5 64 bit. Runs games on 720p displays nicely with reduced settings. I have one on an older machine.But I'd still recommend upgrading your memory if your board accepts more.
However, you could try the card on the RAM you have now and if it grabs too much system memory, then add more.
