Hey there. OK..ive finaly gathered enough funds to buy my dream card The Club3D X1950XTX 512mb, iam going to buy this card on monday from kemplett.ie for 416 Euros. I have an X800GT 256mb and am wondering..When I buy this card what should I expect from it. When it comes to core clock speed,,the X800 is 475 and the X1950 is 650..what kind of difference will this have?? and how do I notice the difference in gaming? the same with the memory speed..the X800GT is 490mhz and the X1950XTX is 2000Mhz..what does this actualy do?? what difference will this have when gaming? Also..the card is 256mb..and the X1950XTX is 512 GDDR4...what difference will this have when gaming?? what does this..GDDR4 do?? as far as I know..its the only card with this GDDR4 memory..but what does this actualy do?? and the same with the 512mb??? any info would be great..ive looked around and cant find any info anywhere to what these memory speeds do for a card and for gamers. Thanks in advance!
