What kind of Video Card should I get?
I Have an Emachines W3609, operating Windows Vista. I have 2g RAM alrdy. Want to get a Video Graphics Card for it. I play world of warcraft so the card will need to be able to handle the game without lagging while playing. I dont want to buy a crad then have to buy a poer supply for it. What should I get that will help my needs?
Assuming these are the system specs for your computer (http://www.emachines.com/products/products.html?prod=W3609)
I wouldn't recommend splurging too much. Your CPU would very quickly become the bottleneck in performance, rather than the current integrated graphics, if you get a powerful/pricy card. Additionally the power supply wasn't necessarily intended to support a powerful GPU. Finally your cooling system isn't designed to keep a powerful GPU cool.
It does indicate that you have a PCI-e x16 full sized slot available (which is good) but it doesn't indicate the it's speed, probably x4 which would be fine for the smaller/cheaper cards that would still improve gaming and general video performance.
Of the 2 GPUs I've bought at BB, I had good luck with my Sapphire not as much with my VisionTek (both were ATI but nVidia is just as good). I'd recommend sticking around $50 bucks.
Sapphire - ATI Radeon HD 4350 512MB DDR2 PCI Express Graphics Card
Sapphire - ATI Radeon HD 5450 512MB DDR2 PCI Express Graphics Card
Sapphire - ATI Radeon HD 4550 512MB DDR3 PCI Express Graphics Card
