Wasn't sure if this is really the forum to be asking this on (As this forum is really geared towards Windows in general) but I thought "What the hell." since there are so many knowledgeable and friendly people here. Anyhow, I am interested in upgrading from my Core 2 Duo E6550 to a Core 2 Quad. I've got a 305W power supply. What I'm really concerned about is pairing it with the other things I have, I don't want to put too much of a stress on my PSU or cause damage to my computer of course. I've got a MSI Radeon HD 6450 graphics card and albeit it only consumes 27W at max, it's a bit of a concern pairing it with something like a Core 2 Quad simply because of the higher power consumption on the processor, simply because on the graphics cards "Recommended Requirements" a 400W power supply is listed... I've run this card with no problems, but this post isn't about that card. So the questions are: Can you recommend me any specific model of the Core 2 Quad (As I know some of them require alot more power than others)? Should I even go with this upgrade and would it be worth it at all? (EDIT) Before you say "Get something better like an i3" this motherboard does NOT support anything above the Core 2 Quad.
