My biggest concern is if the GDDR3 memory will be compatible with my current motherboard? I currently have a 4650 but i kind of want to upgrade. I know i should probably upgrade to something better but i play Eve-Online and i want to run two clients on my computer on semi-decent graphics. i dont want to replace the whole motherboard. at most i want to upgrade my power supply and my graphics card. If there is any other options for under 250 dollars then please throw the suggestions around please. thank you.
