راهنمایی در مورد خرید کارت گرافیک

[habib1370]

سلام دوستان من میخوام یک کارت گرافیک با بودجه 250 بخرم و اصلا درمورد کارت گرافیک ها اطلاعات ندارم یکی از دوستام asus 4850 به من معرفی کردخواهشن هرکی اطلاعاتی درمورد این کارت داره بگه این کارت چیزی خوبی هست یا نه و اگه کارت گرافیکی بهتر از این هست معرفی کنه نظر تون در مورد
asus 5770
sapphire vapor-x hd 5770
چیه کدوم بهتره
مشخصات سیستم من این است
mb asus p5qc
ram 2g
cpu intel e7400 2.80 ghz
power red max 500w

[A.M.D.D.E.V.I.L]

کارت خوبیه فعلا قیمتش تقریبا $125 هست که نمیدونم الان تو ایران چنده
توی بازی GTA IV با گرافیک سنگین توسط مد ENBseries میتونی 14 تا فرم بگیری باهاش (البته اگه enbseries نصب نکنی فکر کنم 20 و چند تایی بگیری

خوب کارت SAPHIRE HD5770 VAPOR-X در بازار تهران حدود 210 قیمت داره و همین کارت با برند ایسوس حدود 240 قیمت داره

نظر من هم 5770 هست از برند سافایر

میشه گفت که یک 5770 مصرفی حدودا اندازه 4850 داره و قدرتش 50-60% بیشتر از یک 4850 هست و همچنین جدیدتر هم هست

البته حدود 250 تومن شما می تونی روی انواع 4890 هم حساب کنی که از 5770 بین 10-15% قویتر هستند ولی مصرفشون هم بیشتره و از DX11 پشتیبانی نمی کنند
