I have been looking around and I think i have found all i need but i still don't know. See i found this video card http://www.bestbuy.com/site/olspage.jsp?skuId=9175705&t... I found this processor (which if you didn't look up this computer that i'm trying to upgrade is the best that my board can take) http://www.tigerdirect.com/applications/SearchTools/ite... and the RAM which agian is the best the board can take http://www.tigerdirect.com/applications/SearchTools/ite... .now (if you looked all that up you maybe able to help me) the things that are getting me is i don't know how strong of a power supply i need and will that card fit in my case and will I be able to keep it cool in the case. (and just cause i want to know will any power supply fit into any case? haha and will this be able to play games like call of duty 5?) So can you please please help me.
I believe your PSU is only 300 watt. That is going to seriously limit your video card choice.
I have seen a lot of posts here lately about folks wanting to upgrade their HP, Dell, or other weak pre-build for gaming. It's a tough road to go. Prebuilds are not upgrade friendly. As others recently found out, even sometimes a simple processor upgrade that "should" work, does not. Faster video cards, either simply won't fit, or the PSU is not strong enough to run them. Trying to change PSU's can then become a pain, because the connectors are propriotory. Just any PSU won't work with the board.
If you do decide to go ahead and shoot the moon for a complete barebones rebuild, (motherboard, CPU, GPU, case, PSU) carry your old drives and spare parts over, then your OEM OS won't work with your new build. *sigh*
It is far better to not buy into the cheap prebuild scenerio in the first place if you want to a be a gamer, and an upgrader.
Where the hell is this BS about OEM OSes not transferring comming from? You may have to track down a non-OEM install disk, but your license will move just fine. Ive only owned one copy of Windows XP, came with a Gateway laptop I bought in 2002. That licence has been used on no less than 5 PCs since then, never a problem beyond having to phone activate a couple times.
