I am planning on building a new system from the ground up.I am having a hard time finding out what the big difference is between AMd and Intel?
Well simply put AMD performs better in most games. Intel performs better in intensive app.'s. There's benches on this site comparing them both. No lack of knowledge on that. PhotoShop runs well on either of them.
And whats the better deal in terms of dollars?
Barton 2500 1.8 gig. I think you'll find AMD XP2400 T-Bread B, 2 gig, 266 FSB @ around $100 or so retail. XP2500 Barton 333 FSB @ $130 or so retail. Those are some great values right now to build a machine around non OCed. Both will OC quite a bit as well.
If you want the best deal going & want to OC hard the XP1700 T-Bread B, 1.4 gig, 266 FSB @ around $60 retail is the one to get. These are getting fantastic OC's. I've seen average 2 gigs out of them posted. 2 to 2.2 gigs I don't think is out of the question.
Any of these CPU's put on a ASUS A7N8X Deluxe v 2.0 MOBO (Fastest AMD Dual Channel DDR MOBO) & 2 sticks of high quality DDR 2700 or 3200 RAM & you've got a whale of a gaming rig.
Vid cards, look to ATI today. A new Geforce card is coming in a couple of weeks. FX series isn't worth getting. Today ATI.
If it ain't broke, take it apart & see why not!
