well ? should'a , could'a , would'a . that's not yes it will ?
thing is that's all the chance you now got to take . me for what I know and see form a lot of threads like yours on cards for a prebuilt I would go with a cheap ''The HP guy says 4xx, 5xx and 6xx (minus 610 and 650) should work''
then he don't tell if that full sized full power cards or the low powered low pro cards ??
like I tend to say ''in the end any upgrade you do is all your own risk prebuilt manufactures only guarantees there computers work as sold to you as is out of the box from there factory with what they put on it , not a drop more . there in business to sell computers not have you upgrading them
you buy ,you try, and hope it don't make you cry
or if you got a local computer shop take it to them and tell them what you want let them put it in and worry if the card you decide on works pay the man if not tell him thanks for tying and move on or have him try other cards he has around till you find he best one that does work as expected .
