I am looking for a video card and everytime i think i have found a good one i see another card that has a higher Core Clock and Memory Clock speed, For example take these two cards and compare and explain them to me in which is better and why i dont no which is better and why.

#1 eVGA 256-P2-N386-AX Geforce 6800GS 256MB GDDR3 PCI Express x16 Video Card - Retail

Core clock: 425MHz
D-SUB: 1
DirectX: DirectX 9
DVI: 1
Memory Clock: 1000MHz

#2 eVGA 256-P2-N391-AX Geforce 6800GS 256MB GDDR3 PCI Express x16 Video Card - Retail

Core clock: 490MHz
D-SUB: 1
DirectX: DirectX 9
DVI: 1
Memory Clock: 1100MHz

I take it the 2nd one is better? Please explain to me whats better.
 
Well it is quite simple. The second one has higher clock speeds therefore it performs fster, and it is a beter card. Just like a cpu. What will be faster a 1.8ghz cpu or a 2.0ghz cpu? Of course you'd think the 2.0ghz cpu right. Same with video cards.
