So I have the Inspirion 570 and a budget of up to $130 dollars, the current integrated graphics card (Radeon HD 4500) needs to be upgraded. I'm looking into something purely for high performance gaming and a long lifespan. NVIDIA seems to be the best brand from what I've researched, not just for their popularity but for their performance. I'm not an expert but I know quite a bit, I figured I would take a shortcut from searching measurements and compatibility by just asking some of you folks. Thanks in advance for any information.
Well assuming your computer has about a 300W PSU (which I'm sure it does, most factory computers come with lower power supplies) There is not much in store for you. the best performance that you can get from a 300W PSU graphics-wise is about an ATI Radeon HD5670 (or 6670, badge engineering). It will give you decent performance for about $70. For what you have though, I would recommend getting a new PSU (its not as hard as you would think, just remember where everything goes) and getting something around an ATI Radeon HD5770.
I'm not an ATI fanboy, its just that as Nvidia has higher performance, bugdet gaming is really where ATI has the realm. The 5770 (or 6770, badge engineering again) will allow you to play the best games on very high settings save for others that you may have to skimp on, like BF3. The 5770 will run you for about $110 or less (I got mine for $100). That will allow you to maybe pick up a better PSU
The things about PSU's though is that it is really the beating heart of the system, not the CPU. My one recommendation is that you DON'T BUY GENERIC BRANDS OF POWER SUPPLIES. Good brands include Ultra, CoolerMaster (most of them at least), Thermaltake, and Corsair. About 500W should do to power a 5770.
Here is a decent power supply at a good price (for now)
I was actually wondering about Seasonic and Silverstone, I was wondering if they were pretty credible.
And you're right, I can't really trust CM after they did the whole eXtreme Power Plus thing where their power supplies couldn't put out the power. I learned that after I bought 2 of them to power some rigs. Luckily one is powering a 9600GSO and one is going to power a 5770, so it is enough.
