I currently have a "SAPPHIRE 100287L Radeon HD 5670 (Redwood) 512MB 128-bit DDR5" and would like to upgrade but keep it under $150.00. Prefer to use newegg for parts. I have a "GIGABYTE GA-890GPA-UD3H AM3 AMD 890GX SATA 6Gb/s USB 3.0 HDMI ATX AMD Motherboard" and "Rosewill Xtreme Series RX750-D-B 750W Psu". I would like to upgrade my video card to play games mostly and I am just asking for some ideas. Any help is greatly appreciated. I do not understand all of the jargon like "Core Clock","Stream Processors","Effective Memory Clock" and a few other ones. Is there a web site that would explain more in detail. But on with my main question is what would any one here recommend for a upgrade for a video card ? I am running a 1920 x 1080 on a 32 inch video screen.
