APPROXIMATE PURCHASE DATE: Next 3 Months BUDGET RANGE: £150/$250
USAGE FROM MOST TO LEAST IMPORTANT: Run Skyrim between High and Ultra (With HD Texture/Mesh mods + other resource intensive mods)
Will currently run Smooth Medium @40FPS and High at 25-30FPS with 10-20 Sec lockups every 15mins - I am thinking that the VRam is full?
CURRENT GPU AND POWER SUPPLY: GIGABYTE ATI Radeon HD 4850 512MB and Not sure on PSU. I think i upgraded to 750W or 850W(Anyone know how I can check?)
I'm thinking that its only the GPU that needs upgrading?
$300/£200 is the top of my budget really. Is there a noticeable difference when compare to a £150 card? If the cheaper card struggles then I'm all for getting the better card, but Id rather not spend money for the sake of it.
Well if it was non GHZ, not really. Stock 7870 vs 7850 is a minimal difference. GHZ is actually quite different, and quite a bit better. Remember, the exact same version of this card in 7850 form is actually only 180 pounds, so its not a giant difference. If overclocked, the 7850 can probably reach the 7870 levels. Lets go with a 7850 then, if you want to save some cash
And currently, I wouldn't recommend to upgrade from a 6970. You wouldn't see much of a difference, might even be worse than a 6970, its just the newer architecture.
I would recommend to wait until the HD 8000's then its a worthwhile upgrade. Upgrading to a 7850/70 wouldn't really help fps at all.
EDIT: Wait nevermind, thought you were upgrading from a 6970 to a 7850/70, I was wrong, my bad.
2nd Edit: Your CPU would be a considerable bottleneck, I recommend you upgrade to a new CPU stat, which would also mean you would have to upgrade your motherboard as well, and most likely Ram. It'll be an expensive upgrade, especially when you want to upgrade a CPU to a different socket type.
Yep, those three will work. If you can get a deal on all three of those, and maybe a further upgrade to your PSU. You say its 750W or 850W, which is more than enough, but make sure and open your case, and it should say on your power supply.
