Some days ago I asked for help when Iw as building my system, well I pretty much finished and here's what I have right now: Asus P5Q Pro Turbo Intel Core Quad Q6600 2x2GB DDR2 1066 Corsair WD Raptor 150GB + 1TB WD Black for storage XFX HD 4870 1GB Antec 650w triple 12v rail Windows Vista 64-bit LG Blu ray/HD dvd drive Well I go over my budget a little and I couldn't afford a monitor at the moment, so I plug my old 17" Hyundai L70N which has a max res of 1280x1024 75hz and 16ms response. My question is: Every game I've installed (I've tried Crysis and Age of empires III) it runs but it flickers anywhere I place the mouse on AOE, I saw diagonal lines when playing crysis and the gun pixelates as I move, is this because of my old monitor? or Windows Vista 64- bit and DX10 are the ones causing this. I'm guessing those because before I was running Crysis with very good performance with only 2GB of DDR2 800 an 8800GT and Windows XP and back then I had a 22" viewsonic, so, the HD 4870 and the 4GB of ram should improve on the performance, however I know DX10 is more a resourse hog, could my current system be a problem to run crysis if yes how come an old game like AOE does have the same problem, I honestly think it's my monitor, but I want to ask to be sure if this problem will be gone next week when I order my monitor or I should look to figure it out the problem right now, BTW I already lower my settings and I see no improvements on this problem, could you let me know what do you think. Thanks in advance for your input.
