Low profile GPU options

my friend has just bought himself a lenovo h520 and now he has decided he wants to game on it... the chassis is extremely small and i think it will need a low profile graphics card does anyone have any sujjestions, hopefuly was looking for something around the power of a 7850 and yes i know the psu needs to be upgraded but i know one that will fit and be able to handle a new gpu such as a 7850 any help would be great thanks. I have found this but don't know if the bracket is compatable http://www.ebuyer.com/413809-xfx-low-profile-bracket-85-t44poool-kyg with http://www.ebuyer.com/434548-xfx-hd-7850-core-edition-2gb-gddr5-dual-dvi-hdmi-dual-displayport-fx-785a-cnjc thanks for any help :)

it wont be compatible..... because the card would be too big for any low profile case....

Ugh, workstation flat box cases are a pain in the ass to upgrade into unless they are full height. He's not going to get medium-high-end gaming performance in that chassis. The best I can come up with is a HD 7750 with a half-height PCB and a low-profile bracket. And that is barely passible as a 720p low settings graphics card.

Ya the 7750 low profile by HIS and Saphire are the best option it will play it 1080p at low to med at decent fps though.

Thanks for the help guys :)
