So i'm building new gaming pc and im looking to hook it up to my 55" rca rear projection tv. I dont have the funds to buy a pc and a new tv at the moment and i really just want to have a pc to play bf3 and other games on rather than my ps3. My ps3 is hooked up to it right now with a component cable so you can get an idea where im at right now. Basically im trying to find out how its gonna look with a decent pc connected with a dvi to component cable and how it will work overall with the refresh rate and what not. The pc will have an i5 2500k, asus/msi 560 ti 1g, 8g of ram and a decent mother board. How much is the graphics card going to matter being that its only 640x480 but its on a 55"? Will it be almost equivalent to an hdtv with a low resolution? I've watched countless benchmarks and other videos on youtube trying to get an idea of how much better it will look than a ps3, but since its going to be on a sdtv and the videos are recorded with fraps im not sure how that will balance out when its on a sdtv. I'm a little new to pc gaming so I would appreciate any info I can get on this set up. Thanks!
No......not even close to as good as a PS3. A PS3 puts out 720p then upscales it to 1080i. You are going to be using 480. It's going to be nearly unreadable. The graphics card is going to be doing almost nothing. At that low a resolution the CPU will do most of the work in most cases.
I've set my monitor to 800x600 and that is nearly unusable. Just basic Windows windows go off screen all the time. I can't image lower res than that.
What is your budget? We can definitely help get a PC and a monitor to all fit in the budget and game pretty well. Trust me, even a mediocre monitor sitting 2-3 feet away from you looks really, really good compared to a SDTV.
