Do i need a upgrade for HD-4850

Yes, you should get a more powerful GPU but only if you upgrade your monitor. Without a high-res screen, there's no point in a too powerful system. Even that 2500k seems a bit overkill.

Sure you can upgrade - as you said, you're getting decent framerates, but DX11 is nice, and 60fps is great. Though anything over an HD 7850 would be overkill (not to mention overpriced), as it will max any game on ultra at your res. If you have no problems with your current monitor, then keep it - the most important component at lower-resolutions is your CPU and you've got one of the strongest ones out there.

The question is, are you hoping we talk you into buying, or that we talk you out of buying?  

If you're hoping we talk you into buying:
You would see a performance bump from even a 7770, but if you want to run the card for another 4 years, I'd go for the 7850 (or 7870 if you think you'll upgrade your monitor in that timeframe and want to future proof). However, if you're on the fence about the purchase, wait another month, since nvidia is nearing the launch of their midrange cards they may offer better values and/or force AMD prices down in 78xx series.

If you're hoping to be talked out of buying:
There is nothing wrong with being happy with what you've already got. If 30fps doesn't bother you, then why bother; if you wait 3 months you'll likely save 50$ or so, if you wait a year you'll probably have access to the 8xxx and 7xx series and have a better upgrade at your price-point. You'll also have a better idea if/when you'll want to upgrade monitors so you can buy the appropriate card.

Hey!

You should get a 7850, at that resolution you don't need that munch gpu power. At that resolution a 7850 should allow you to play your games on max settings with at least average of 50-60 fps.

After reading all this.. I am thinking of buying a new monitor and a good strong GPU which should be able to run all games on max setting at 1080p for at least 3-4 years, which MSI HD 4850 has done for me from last-4 years. Because on 2008-09 4850 was a champ and still it has a good run in my rig. Like i said my budget for GPU will be $400. if i consider i can manage $430-$450 max not more then that. please suggest me some good GPU. Currently i am having a 500W PSU. do i need to change that also ?

What kind of PSU do you have? AMD states that the 7850 requires a 500w PSU, so it's likely that it's fine, but if you've got a cheapo you may wanna upgrade. How many 12V rails and what current do they supply?

The new GTX 670 is the best card for $400 - but you'll have a hard time getting your hands on one. I suspect AMD will be dropping the price of their HD 79xx cards in response, so you could wait a few weeks and get a better card at $400. Though even the HD 7950 would last you several years in games.

I was also thinking of getting a GTX-670. considering the price and performance its a good deal. In online stores it is almost out of stock. Will it be available in retail shops ? Basically I am from India. For a software development project I will be traveling soon to Portland for 2 months. On that case i was planning to get on GTX-670 from there it self, as it is almost $549 in India.

But I have some doubts.
1. Will I be able to get the warranty on GTX-670 in India too ? And I wont be able to perform a test on it as long as I will come back to my home.

2. Will it work fine ? As it is just lunched, I am unable to put faith on it.

I don't think you would be able to get warranty support for a card purchased in America and taken overseas; but I'm not 100% sure. I would recommend finding some way to test the card you purchase before going home (maybe find a gamer amongst your coworkers and see if he is willing to use the card for a day or two, as long as his PC can support the power requirements).

Otherwise, if you purchase from a computer store, simply explain the situation and see if they will run the card on their bench system for a few minutes to make sure it is not a complete DOA. Alternatively, you could probably pay a computer shop to test the card that you bought from newegg or something, but that eats into the money you are going to save.

It would be a risk to count on the warranty, and there certainly is the chance you could wind up with a bad card, so be wary.

You won't need a GTX 670 if you don't buy a higher resolution monitor. At your resolution, a 6850 will be enough to max out most games out there.

As I mentioned above, I will upgrade both monitor and GPU.

Thanx for the info. After some conformations I will going buy either GTX 670 or HD 7950 from a local shop as i dont want to take risk
