If you only changed one thing and performance was degraded, it heavily points towards the card, not existing hardware. If it was existing hardware, you'd really just be wondering why you didn't see as much of an improvement as you expected.

Regarding the video card, you did downgrade unfortunately. Memory size is far from the most important spec, especially if you aren't maxing the resolution or running multiple monitors or using ultra high texture packs. Your first bottleneck is going to be GPU core and memory clock speeds, and if you look at the specs off nvidia's site, you can see why:

8600GTS:
GPU Engine Specs:
10.8 Texture Fill Rate (billion/sec)

Memory Specs:
128-bit Memory Interface Width
32 GB/sec

620:
GPU Engine Specs:
11.2 Texture Fill Rate (billion/sec)

Memory Specs:
64-bit Memory Interface Width
14.4 GB/sec

So you actually downgraded on memory bandwidth by a lot. From http://www.gpureview.com/memory-band...ticle-356.html - "The amount and speed of the memory matter very little in comparison to the overall memory bandwidth. If you want a card with good memory, this number says it all."

This measures how quickly the card can access said memory. Having more doesn't help if it takes longer to access it.

If you can spend a little more, you may want to return it and check out something like this: http://www.amazon.com/EVGA-GeForce-1.../dp/B00966IU4M
