Assuming that I will be using a Gigabyte GA-8IRXP which states on its product page <A HREF="http://www.gigabyte.com.tw/products/8irxp.htm" target="_new">http://www.gigabyte.com.tw/products/8irxp.htm</A> that 200/266 memory can be used with it (pc2100), is it worth the 20-30 bucks more for pc2700. How much of a performance gain can I expect?
