Hello dudes its finally time for me to make an overhaul on my current computer. I have been using my DX420s http://support.gateway.com/s/PC/DX400/1200393/1200393nv.shtml for some time now, bought a Nvidia Geforce 9800gt for it and upgraded it to 4 gb's of ram. I have 2 internal hard drives and an external seagate 500gb hard drive. Everything else is stock. I'm thinking its time to replace my very outdated dual core processor. From what I understand I might have to get a new motherboard to fit a more powerful processor such as an i5? Also thinking about upping my RAM to 8gb (for audio work). My only other question would be is my graphics card still relatively good? The reason I ask is because I tried running Skyrim (just got it) and for the first time in years I bought a game that was very laggy even with low settings (I can run BF3 maxed out though?). Another question that just came to mind, is there a way to see if I'm getting the most out of my computer and there aren't any things slowing it down? Is there any way to configure how the hardware runs better? Sorry for the crazy amount of questions, i'm pretty computer savvy I just have been out of the hardware loop for a few years now. Thanks!
