hey there, lately Iv'e been wanting to upgrade my graphics card but i don't trust myself with compatibility checking. If someone could be generous enough to find me a graphics card that is compatible with what iv'e got (also anything under $500 would be great if possible). this is the motherboard i have: http://www.gigabyte.com/products/product-page.aspx?pid=4305#ov (if more information is needed to find a compatible one let me know and ill post what it is you need to know) Thanks to anyone who helps!
