Need help deciding which to buy

[Themkman]

hello

Im looking to build a basic gaming system to run battlefield 3 and farcry 3 ect ect, I dont have much money £500 tops to spend on the base unit. ok so i already have a graphics card i bought for my current pc but it is dated and just crashes when i install the new card, so i thought i might aswell just build a new system.

my current pc is a stock pc bought from currys,

The graphics card i bought was a Nvidia gtx650

so i would like to keep that but i need the rest of the parts so im stuck between these 2 deals? i only want this pc for gaming, nothing else
