Need help deciding!

post #1 of 4
Thread Starter 
I (stupidly) perused the local craigslist and saw quite a number of good deals on GPUs. So now I MUST spend some money to make a needed upgrade to my work PC that I am on a lot and would not mind playing games on. It has an unlocked Sempron 145 running @ 3.6GHz with 4gb ram, a 5450 and a 1600x900 monitor. It plays BF3 at 720x480 averaging 30+ fps, but it looks horribad.

So my predicament is...I found a Sapphire 6870 that I can pick up tomorrow for $120. However, seeing as I have a dual core, how bad would that affect its performance if any? I am unsure if it will be any issue.

My other option is that I can get a $50 phenom quad from Microcenter, and grab a 5770 for $70 locally.

OR just save money and grab a local 5670 1gb for $40.

I really want that 6870 and am leaning towards that cause I used to have one with my 2500k before I got my 560 ti.

From a gaming perspective, you probably won't experience too much of a bottleneck from the CPU. There is pretty much going to be guaranteed performance increase since the GPU will allow you to run BF3 on higher settings/resolution. I'd say go for it.

Upgrading to a quad core will allow you for better multitasking (while running BF3 or other games) which you may have trouble with with the Sempron.

Yea, I do not do too much heavy multitasking, so I am not too worried about the CPU. I was just thinking that at 1600x900, load may be more on CPU than GPU.

Well the Quad Core CPU will definitely help performance overall. But based on the deal you've found I'd get the 6870 first and maybe upgrade to the Phenom later on down the road. In any case, you will be able to run BF3 with better frames smile.gif
