Im looking forward to buying this card Sapphire RX460 2GB GDDR5 11257-00-20G No overclock nothing 2GB DDR5 memory is this good ? And will this damage my CPU or something over a long-term usage? Thanks for answers ^^
In this class of videocard, entry level performance, 2gb is great and no you don't need overclocking. Two reasons, first this class of card is too slow to make use of more memory. Second, this class of card is slow enough that overclocking is not going to give enough of a boost to performance to make an unplayable game playable. What I mean is if the regular clock card gets you 30fps in a game and the overclocked version gets you 35fps in a game, that's the same for all practical purposes. Those 5fps extra won't make the experience all that much better.
Adding a new card will not damage your CPU. That 'bottleneck' people mention just means that if you had a faster CPU, the videocard would perform better than it will perform with your slower CPU. Nothing gets damaged either way.
