I have a AMD Phenom quad-core 2.50GHz processor. Will my GPU not run its full
potential with this processor, its a ASUS GT440 1GB GDDR5 822MHz overclocked.

Why is it that this graphics card can play every game skyrim on max with little lag but its not really a expensive card? Only demanding game i havent played this card with is battlefield 3 and crysis.

yeah maybe at a resolution of 800x600

thats (1280x1024)/(1080x1920) = .63 or has only 63% of the pixels that a 1080p screen has. ill take 1080p and lower graphics settings over that resolution any day.

Okay I dont know much about resolution effecting graphics so can you explain it like your talking to a child please : (

the more pixels the more of a load the gpu has. if you were to play your rig hocked up to a 1080p monitor i would suspect about a 40% decrease in performance because of the added load. Decreasing the resolution has the opposite effect.

at the same time though the lower your resolution the more stress you put on the cpu because now the gpu can spit out a lot of frames per second making the cpu have to put out more as well.

1080p is HD and mine isn't right? Also what I should do if that is correct is buy a 1080p monitor then find a happy medium resolution for my gpu and cpu like how you suggested (1080x1920)?

you could buy a new monitor that supports 1080p but your fps at that resolution will not be good. you would need a new gpu to play at good settings at 1080p

Ill stick with what i got but i will be getting a new comp soon so thank you know i know i need a new monitor to support 1080p also i want a GTX 560ti that will run 1080p for sure but how good of a cpu should i get? If i can afford it too i want a 3.5GHz i5

Ya the i5-2500k was what i was talking about. I might just have to get the i3 though. Ya i plan on getting another 560ti a bit after i build new comp and SLI them.

doubtful. define exactly high settings.

if you have over 4gb of ram preferable 8gb of ram then the only things that affect gaming online is cpu and gpu assuming you have a suitable internet connection or wireless card.
