BleepingComputer.com: Processor help

I was planning on getting a PC but my budget has lowered to $4xx. I play games often but I don't really need to play games on max settings. I have no clue what to do with processor speeds. I saw a computer with a dual core 2.5 GHz processor for 400 something but I don't know if this could run a game such as Crysis on low settings. It says 2.8 but doesn't dual core make 2.5 double? I'm not the greatest with computer as you can probably tell. Please give advice if you can.

i dont use intel....but if ure pc is AMD i think i can help.

i use this:: http://www.newegg.com/Product/Product.aspx...N82E16819103808 for my gaming rig...it is the second best AMD makes and runs everything i throw at it flawlessly including crysis on highest settings

but i suppose u r looking for cheaper... http://www.newegg.com/Product/Product.aspx...N82E16819103252 this i think should be able to run crysis easily, but please somebody else correct me if i am wrong....also what is ure budget for the processor only??

hope this helps a little...im not a pro by any means

My processor $ cap would be 100$ I plan on buying a pre--build then upgrading things such as the CPU. This is what it comes with// AMD Athlon™ X2 dual-core processor 7550 \\ Somy goal would be a 440$ PC that I could upgrade on what I need such as Graphics,Ram and/or the CPU.

Upgrading pre-built PC's can be tricky since some of them use proprietary or custom-made motherboards. This means you may be limited in terms of which CPU's you can upgrade with. If you are a gamer, you should get, at the very least, a dual core CPU with a clock speed of 2.8GHz. or greater. If you buy a prebuilt system that allows for AMD's AM3 CPU's, I would go for a AMD Phenom II X2 550 Black Edition Callisto 3.1GHz. AMD's CPU lines are split between the Athlon II and the Phenom II. For users who want a more robust CPU, the Phenom II's should be considered. The Athlon II's are meant for low-cost builds and don't have some of the features of a Phenom II. The old Athlon I's (a.k.a just Athlon) are older and not as efficient as the newer ones, let alone the Phenom II's. That specific Phenom II is Black Edition so it can be easily overclocked. Intel's lineup is more complicated in that they have the Core 2, Celeron, Core i3, i5, and i7, most of which uses different sockets and require different motherboards.
