<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">I am using a Gig ethernet dual 450 machine with 1GIG of RAM and a superdrive. When playing video, such as youtube or even videos from iTunes, my frames skip and it's overall a pretty disappointing experience. I have the opportunity to upgrade this machine. I am looking for the processor upgrade at the <FONT class="Apple-style-span" face="Verdana" size="1"><SPAN class="Apple-style-span" style="font-size: 9px;">PowerLogix PowerForce Series 100 DUAL G4-7455/1.0GHz </SPAN><FONT class="Apple-style-span" face="Helvetica" size="3"><SPAN class="Apple-style-span" style="font-size: 12px;">and runs around $280, and for video, an ATI Radeon 9800 w/ 256MB which runs $250, both prices are new units. Once I look at the cost to upgrade the machine to a moderately useful setup, I feel I could get a similar setup with the purchase of a used machine purchased on ebay. I could then turn around and sell my old unit for about $300. My computer isn't used for anything particularly processor intensive other than editing photos in iPhoto. I am just looking for some opinions on where I get the best bang for my buck, and whether a machine replacement isn't just as beneficial as a couple of new parts. Obviously, I would love to buy something in a used G5 machine, but do I need that much processor for my menial tasks.</SPAN></FONT></FONT><DIV><BR class="khtml-block-placeholder"></DIV><DIV><FONT class="Apple-style-span" face="Verdana" size="1"><FONT class="Apple-style-span" face="Helvetica" size="3"><SPAN class="Apple-style-span" style="font-size: 12px;">Thanks for any and all advice.</SPAN></FONT></FONT></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Mark</DIV></BODY></HTML>
