Looking for advice on what GPU to buy

Hello all. I recently built a new PC with the help of this forum and took the advice you all gave me on focusing on buying a top processor and motherboard and waiting on a GPU til i can afford one. Well today is the day. I have been playing games on the integrated HD 4000 graphics from my i5 ivy bridge but im ready to step it up here are the specs

the power supply i have is a cheap 500 watt psu that came with the case.

I am looking to game and watch HD video. My monitor is only 1600 x 900 as it is older but i have it hooked up with DVI and it seems to display HD movies very well.

i was looking at this HD 7770 as it is on sale and seems like it would do me just fine

Feedback is much appreciated and i hope i provided all the info you guys need. If not just ask and i will fill it in

  1. What case do you have? :) I'm a little concerned about your PSU.

    However, I don't think you should run into problems if you don't overclock as the HD7770 and 3570k are very power efficient.
  2. What you should buy depends on your budget. The graphics card monthly price comparisons are quite accurate. $125 for a 7770, $200 for a gtx 560 ti, and $400 for a gtx 670 are my usual suggestions. For 900x1600 a 7770 should be adequate. Also 7950/7970 are apperently getting quite competitive in price and driver improvements as well.
  3. Here is the case

    http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=6430027&CatId=1845

    The power supply is loud and i have heard complaints about them crapping out but i will deal with that when the time comes. For now it seems to be holding up ok as i run my pc all day and night and never have a hiccup. I will buy a new PSU when i get the money for a good one. I havnt overclocked and dont plan on it until i can get an aftermarket cooler and better PSU so overclocking is not going to be part of the equation until then. For now i would just like to be able to run games like Battlefield 3 on medium to high and stuff like Star Wars The old Republic and WoW on as high as they can go. Will a 7770 handle this?
  4. Yes it should. Especially at your resolution.
  5. An HD7770 should be able to handle those games at your resolution without a hiccup. However, I'm concerned about your PSU...I'm not even sure if it can output it's rated wattage of 500w.

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026 I would definitely get this along with an HD7770 if you can afford it.

    Sorry i forgot to put my budget. I am looking to spend from $100 to $140 the 7770 line is mainly what im looking at because of its performance for its price is good from what ive heard

    ok thanks for the advice guys. I will be getting a new PSU at some point. If the one i have currently doesnt put out enough wattage to run the GPU then it will be sooner rather than later. I may be able to scrounge the funds together to get both at once but who knows. I def want to get a GPU already though. playing these games on low/medium settings is getting old.
  8. You should be completely fine without buying a new power supply and just getting the gigabyte o/c 7770 card. It's a wonderful card, I've already used it in 2 builds. The amount of risk you incur by using a budget level psu is minimal.
  9. Just keep in mind with cheaper PSU's, when they blow, they can take other components with it such as your motherboard, CPU, HDD, which will ultimately cost you more money to replace than to get both a quality PSU and GPU at once.

    I would definitely recommend delaying the purchase until you have enough funds. Or, get the GPU or PSU first, then buy the other later.

    If you're referring to the wattage the PSU is rated for, yes, it should be fine for even a GTX660 Ti. However, keeping in mind how much it costs and how generic it is, I wouldn't even want to use it. I'm more doubtful it can even output 500w of power IMO.
  11. Newegg's worst-case-scenario psu wattage calculator says he needs 340w. It is extremely unlikely his psu can't handle the 300w it will probably be usually using in more realistic calculations.
  12. Oh really.. Read this review, apparently there exist PSUs that are rated for 700 watts but die on less than 300 watts:

    @ kevin83

    This is what I was talking about, there's too many things that could go wrong with generic PSU's, so I will NOT recommend/trust them AT ALL.

    I've personally experienced this (my brother, actually). He bought a Raidmax PSU that was rated at 530w. He thought his rig won't even use 300w (PHII X4 955 + HD6850), so he went ahead using it. Surprise, surprise, when a power surge struck, guess what went out? His PSU and his motherboard. Even before the power surge, he was experiencing HyperTransport errors... which from my understanding can be caused by voltage fluctuations from the PSU.
  14. Lol ok i feel like a dumba$$ as you were all discussing whether it would handle it or damage it i decided to take a nice close look at the piece of sh!te psu thats in my case and guess what. IT DOESNT EVEN HAVE A 6 OR 8 PIN PCIE adapter on it. They knew when they made this thing that it would most likely explode if anyone tried to run a GPU off of it lol. Cheap bastards. Well looks like i have no choice but to upgrade PSU also. So now i guess the question is what do you think i need realistically to run my rig. I like the corsair 430 but is there anything as good but cheaper? i am stretching my budget here to get both
  15. Realistically saying, you could get by with this PSU - http://www.newegg.com/Product/Product.aspx?Item=N82E16817151072

    But considering it costs just as much as the Corsair I have listed, it's a no brainer to go with a Corsair.
  16. You shouldn't judge something off of horror stories and bad apples in the manufacturing community. There is a good chance that even running the 7770 off of a 2 molex to one 6 pin adapter with his psu will work fine. If it doesn't the chance that it will fail in a catastrophic fashion is slim.

    If it doesn't work then he should put a new psu in the system.

    I would still prefer not to take the risk :sarcastic: not to mention I would recommend an upgrade anyway (some others probably will as well) so why not upgrade now?
