I am thinking of buying a new nvidia gt 520 for my 4 years old pc with pentium d3.0 ghz processor and 2 gb ram. I am not a hardcore gamer so i have opted this card( it suits my budget well).
Now i have two options one is
1) XFX gt 520 1gbddr3( 810 mhz core ,1066mhz memory speed) it has an extra fan on it for cooling.
Which one should i go for? does this difference in memory speed affect the performance greatly?And also is 'silent cards' a good option( sound is not a problem for me)? which will have good heat dissipation?
IS xfx a good brand( its a little costlier than asus for this model)?
I also have one more doubt. I am having a n xfx geforce 7200 gs now and is running on latest driver which also supports the gt 520. so do i realy need to uninstall the running drivers from my pc before replacing the card?
I personally prefer Asus, especially since I've heard a lot of negative comments about XFX lately. Asus usually have higher clock speeds, better cooling and most of their card (I think the GT 520 included) have a 3 year warranty.
the drivers wont be an issues as your still staying with the same vendor chipset. i look at the power supply you have and the output of it and the 12v leg. i would check that the ps can handel the wattage of the new card.
