I want to upgrade my graphics card from a ATI Radeon HD 5450 to a Radeon HD 5850, but I'm not sure how I want to go about doing this. In the first place, I want to make sure my computer will be able to upgrade with these specs:
HP Pavillion Elite HPE
CPU-- 2.3 GHz Quad Core processor
CPU Speed-- 2.8 GHz
RAM-- 7.9 GB
OS-- Microsoft Windows 7 Home Premium Edition Service Pack 1 (build 7601), 64-bit
Graphics Card-- ATI Radeon HD 5450
Sound Card-- Kinoni Audio Source
Processor-- AMD Phenom(tm) II X4 925 Processor
Assuming my computer can be upgraded at all, I've gotten a few reccomendations to upgrade to a Radeon HD 5850. If I've heard wrong or the Radeon 5850 isn't a viable option for me, I'd like to know before I do anything drastic.
Also, I've never attempted to change my computer's hardware but if it's possible I'd rather do it myself than pay someone to do it. Is it not advisible to do that? How difficult is it to swap my graphics card? Any tips?
