But I came accross a doubt, what graphics card should I buy? There are only a few to choose from, the two I selected are undoutably the best ones in the list they are:
*XFX HD 4770 512MB GDDR5 - price 1.145kr
*Gainward 9800GT 1GB GDDR3 - price 1.150kr
I know that the 9800GT has more memory but the 4770 has GDDR5. And I know that the maker of the 4770 is better, and has a better cooler too. But again the 9800 has awsome memory. Any expert tips anyone? Thanks
Of the two the Radeon 4770 is generally faster. The Radeon 4850 is a little faster and generally a little cheaper than the 4770 though. It's only cavet is that it runs a bit hotter and uses more power too. Considering the current state of things it may be a good idea to just spend a little more and go with a Radeon 4870 or a GTX 260.
since performance is about the same, we could look at other things...
Power: The 4770 uses less than the 9800gt, though with your high quality PSU there, it wouldn't really make a difference.
Heat: The 4770 does produce less heat, though if you have parts like the ones you've listed i would imagine your case isn't half bad either, so heat may not really be a concern.
Overclocking: Because the 4770 is a smaller nm chip, it tends to have more overhead and will more than likely (because it differs chip to chip) OC better.
What really matters? : They are about the same, the 4770 shines a little brighter because it is newer. What i would say it comes down to is do you have a preference to ATi over Nvidia, what is the cost difference, and what brands (IE warranty).
If i had the choice between the two, i would take the one with the better brand that offered the better warranty.
*also to note, since your MoBo won't support Xfire or SLi, i left those out, but if it did that would of course need to be taken into consideration.
ASUS Radeon HD 4850 512MB GDDR3 PCI-Express 2.0, 2xDVI, HDMI, HDCP [info] -142.06 <---- My Personal opinion, the 4850 is the best card, the brand choice is just brand loyalty, never had a problem with any of my asus products.
