I have a Dell Studio XPS, it is about two years old and I am trying to upgrade the GPU to handle newer games coming out. Here are the specs--
Dell Studio XPS 435MT
Windows 7 64 bit
Intel Core Quad i7 2.8ghz
8 gb ram (probably upgrading to 12gb or 16gb though)
Radeon 4850 HD
my Dell service tag is 51LNNK1
I think the PS is only 300 watt this is the model # PS-5361-2 ; which I am sure is going to be a problem.
The computer runs great but recently the video card has been overheating and it causes my PC to automatically turn off especially in heated moments of battle. I want another tier 1 video card preferably one I could play games on higher settings. Games I play are Battlefield 2, 3 when it comes out, Team Fortress 2, Call of Duty Black Ops, Starcraft 2, World of Warcraft. Most games run well on medium-high settings but the Ultra Settings would be great. I can spend 150-400 but prefer to keep it around 300. It would be awesome if the card ran quiet too because the Radeon 4850 HD is so loud when I play games or watch HD videos.
Any Suggestions on how I should go about upgrading the last Dell I will every buy?
If it's only a Dell 300watt PSU then the 4850 probably isn't getting enough power.
Unless you have lots and lots of Windows/Applications open then theirs no need for more than 8GB of RAM.
Either a GTX560ti or a 6950 will fit in your $300 budget but you could get a GTX570 if you really wanted to stretch it to the full $400.The GTX570 can be had for $280 after MIR and it's probably your best performance per cost ratio you can get.With either choice your going to need a new PSU.The PSU that eleclerc suggested is good but it's a bit pricey and doesn't have enough wattage for future upgrades.
