my cable management specs: core i5 750 @ 3.8 ghz 4 gigs ddr3-1600 g.skill ripjaws 250gb samsung , 1tb western digital,320 gb western digital Visiontek 4850 corsair hx 520. 10 fans in total. now onto my question. I want to get a 5870 will i need to get a new psu for it or iwll my hx520 be enough to power it safely? now about monitors: i've been look at the Samsung 2494SW and Samsung 2494HM (is the height adjustable stand and hdmi worth t he extra 30$?) and how is it for gaming? my current lg has a 2 ms response time. the other monitor i've been look at as well is a LG W2442PA-BF 24IN Widescreen LCD Monitor Black 2MS 10000:1 300CDM 1920X1080 1080P HAS Tilt HDMI DVI.,but i can't find any reviews of it other then on the site i can buy it off of and it is seemingly plagued by dead pixels.
