Just put a 500watt PC POWER/COOLING psu in my Dell XPS 420. Now i need a card. I would like to stay with ATI radeon HD 4870 PCIexp. 1024 (unless there is a better way to go) but i don,t know which manufacture is the most reliable( such as XFX, DIAMOND, asus, the list goes on. would like to stay between $200/&300. Thanks in advance Lee
I would be looking at an HD5770 instead. It's about $10 more. Not quite as powerful, but it's close and it's much more power efficient and DX11 compatible.
Or, if you want to max out your budget try to find an HD5850. Much better than either of the other two but also close to twice as expensive(used to be $260 but it's now up to $310 and hard to find.)
Unfortunately I'm currently going to RMA it because it runs way too hot. With my side panel on I idle at over 70 celsius and it has hit 98celsius under load with the stock fan speed! I don't know if it's a defective card or if my case cooling just sucks. But I don't believe cards should ever hit 98 celsius on stock speeds because it makes my whole case run way hot.
Your call though if you want to chance it with the XFX. Seems like others have gotten good temperatures with it.
