Do you know exactly which model the processors are (Codename, specifically is useful)? Both AMD and Intel have made multiple processors with those names. It’s a debated question, but in my opinion, looking at when those two processors were made, Intel’s ahead of the game. As far as the BIOS/overclocking question goes, you can just boot up your BIOS and check if you can modify the settings or not, but overclocking is one of those “if you have to ask…” fields in some respects – there are standards and accepted practices but not much by way of hard, scientific data.
You’ll have to check to make sure both sticks of ram can take the same timing and you might want to set up the 320 as your OS drive with your standard programs (internet, document) and leave the 500 for media and games. That way your system will be capable of accessing OS files in parallel with game files, not that it’ll be a noticeable difference anyway.
well more ram is always better until its hits it max which is 4gb for 32bit windows and it get weird once it it pass 3gb because windows only shows 3gb. also windows vista takes a lot of ram so there are reason to get more ram
Depends on your OS. Vista will use all of the RAM in your system as Cache, where XP uses what it needs for the services and programs and the left over ram just goes to waste. If you need more than two gigs on your xp machine to run SF4 then your running too much shite in the background. I bet you 4 internet dollars that your frame rates wont notice a difference in XP between 2 and 3 Gigs of Ram.
