So I would like some human advice on the above topic, instead of just looking at the numbers. I have the 550, but I could get the 670 if it's really worth it, regardless of the price, as I do not want a minor upgrade. Now, on here http://www.hwcompare.com/12519/geforce-gtx-550-ti-vs-geforce-gtx-670/ , it seems that the upgrade is not as significant as you might hope, but on tomshardware.com's tier system it is 6 tiers higher than mine, so it seems like a viable upgrade. So I am a bit uncertain whether it is really a good upgrade for me? Please help, anyone Anyone who did a similar swop who could give me advice would be a nice bonus!
