Good day all. I hope all is well for everyone's first day of 2011! Ok, down to business. My current system is making me question whether or not I can smoothly play Blu-Rays/HD quality youtube videos with my current hardware. My current system is: OS: XP 64 bit. CPU: Athlon 64 3800+, orleans core. RAM: 4GB DDR2 @ 402MHZ (this is 2x2GB sticks, shows up as single channel, should be running dual, both sticks are in the same colored slot, any help here?) MB: MSI K9N Platinum VIDEO: ASUS GeForce 7900 GT/GTO 512MB Obviously I think my biggest problems lie within still running a single core CPU, and that video card is 3 years old now, or maybe it's 4? Any idea's if this is enough? Thank you!
