Anyway, Im probably not making the purchase until probably 4 months down the road, Due to money, So my list will be constantly changing as these parts go out of date, or become cheaper until the day I make my purchase.

Anywho,

Is there a better graphics card out there, My PSU can handle, for that price or lower "165$"

I am only a strict ati/amd guy On processors, I kinda am too on GPU's but I can pass if You can list a better NVIDIA chip, under said price.

Thanks everyone, for replying or just scrolling through my message.

Godbless and have a great day!

ask again in 4 months

More info, preferably a chip that doesn't make me change the MOBO. *Note* I was not bumping.
